Solve for x, when y = 5.
9x + 2y = 10​

The correct option will be option C: Multiply/divide both sides by the same non-zero constant.

Step-1: we have to balance each side by simplifying the equation

Step-2: add/subtract constant term on both sides of the equation to separate variable and constant term on both sides

Step-3: divide the coefficient of the variables on both sides.

So according to the question,

the given equations are:

AAA: 3(x+2)=18

BBB: x+2=6

We have to find a way from equation AAA to Equation BBB

from the above equation, it is clear BBB is factor AAA.

to get BBB from equation AAA, we have to just divide 3 on both sides of the equation AAA.

Therefore option C will be correct as 3 is a non-zero constant. we have to divide both sides by this same non-zero constant.

Therefore The correct option will be option C: Multiply/divide both sides by the same non-zero constant.

Answer:

4(x+3) = 20

divide both sides by 4

x = 2

Step-by-step explanation:

The value of the number is -9/10.

Let the number be x

Two times the quantity of eight times a number plus two will be written as:

= 2(8 × x) + 2

= 2(8x) + 2 = 16x + 2

Three times the quantity of two times the same number minus 7 will be written as:

= 3(2 × x) - 7

= 3(2x) - 7 = 6x - 7

We will equate both values and this will be:

16x + 2 = 6x - 7

Collect like terms

16x - 6x = -2 - 7

10x = -9

x = -9/10

In conclusion, the value of the number is -9/10.

Answer:

[tex]Reduction = \$3300[/tex]

Step-by-step explanation:

Given

[tex]Pay\ for\ 52\ weeks = \$55,640[/tex]

Required

Determine the reduction when paid is reduced to 49 weeks

First, we need to determine the weekly pay

[tex]Weekly\ Pay = \frac{\$55,640}{52}[/tex]

[tex]Weekly\ Pay = \$1070[/tex]

Next, is to determine the pay for 49 weeks;

[tex]Pay = Weekly\ Pay * 49[/tex]

[tex]Pay = \$1070 * 49[/tex]

[tex]Pay = \$52430[/tex]

Subtract the 49 week pay from 52 weeks pay to get the payment reduction;

[tex]Reduction = \$55640 - \$52340[/tex]

[tex]Reduction = \$3300[/tex]

6.99 dollars is 41.94

Answer:

B: -1.94

Step-by-step explanation:

First, you would want to multiply 6 and 6.99

You should get 41.94.

Finally, subtract 41.94 with 40.00. (41.94-40.00).

You should get -1.94. The reason why we add a negative sign is because the total cost of the 6 bikes is more then what she payed with.

Answer:

x = 3

x = (-1)/2

x = 13/4

Step-by-step explanation:

Solve for x:

(2 x)/3 + 15 = 17

Put each term in (2 x)/3 + 15 over the common denominator 3: (2 x)/3 + 15 = (2 x)/3 + 45/3:

(2 x)/3 + 45/3 = 17

(2 x)/3 + 45/3 = (2 x + 45)/3:

1/3 (2 x + 45) = 17

Multiply both sides of (2 x + 45)/3 = 17 by 3:

(3 (2 x + 45))/3 = 3×17

(3 (2 x + 45))/3 = 3/3×(2 x + 45) = 2 x + 45:

2 x + 45 = 3×17

3×17 = 51:

2 x + 45 = 51

Subtract 45 from both sides:

2 x + (45 - 45) = 51 - 45

45 - 45 = 0:

2 x = 51 - 45

51 - 45 = 6:

2 x = 6

Divide both sides of 2 x = 6 by 2:

(2 x)/2 = 6/2

2/2 = 1:

x = 6/2

The gcd of 6 and 2 is 2, so 6/2 = (2×3)/(2×1) = 2/2×3 = 3:

Answer:  x = 3

______________________________________________________

Solve for x:

3 x - x + 8 = 7

Grouping like terms, 3 x - x + 8 = (3 x - x) + 8:

(3 x - x) + 8 = 7

3 x - x = 2 x:

2 x + 8 = 7

Subtract 8 from both sides:

2 x + (8 - 8) = 7 - 8

8 - 8 = 0:

2 x = 7 - 8

7 - 8 = -1:

2 x = -1

Divide both sides of 2 x = -1 by 2:

(2 x)/2 = (-1)/2

2/2 = 1:

Answer: x = (-1)/2

_______________________________________

Solve for x:

4 (2 x - 6) = 2

Divide both sides of 4 (2 x - 6) = 2 by 4:

(4 (2 x - 6))/4 = 2/4

4/4 = 1:

2 x - 6 = 2/4

The gcd of 2 and 4 is 2, so 2/4 = (2×1)/(2×2) = 2/2×1/2 = 1/2:

2 x - 6 = 1/2

Add 6 to both sides:

2 x + (6 - 6) = 1/2 + 6

6 - 6 = 0:

2 x = 1/2 + 6

Put 1/2 + 6 over the common denominator 2. 1/2 + 6 = 1/2 + (2×6)/2:

2 x = 1/2 + (2×6)/2

2×6 = 12:

2 x = 1/2 + 12/2

1/2 + 12/2 = (1 + 12)/2:

2 x = (1 + 12)/2

1 + 12 = 13:

2 x = 13/2

Divide both sides by 2:

x = (13/2)/2

2×2 = 4:
