[tex]2x+4y=120[/tex]

What could be x and y?

Answers

X= 60 or (60, 0) and Y = 30 or (0,30)

Answer:

20 for both x and y

Step-by-step explanation:

if we substitute 20 for x, we get 2x20 which is 40.

If we substitute 20 for y, we get 4x20 which is 80.

80 plus 40 is 120.

Hence the answer is 20 for both x and y

Answers

Answer:

16/15

Step-by-step explanation:

Ratio: 3/4 : 4/5

Whole number ratio: 15 : 16

You need to divide both sides by 15 so you can turn 15 to 1
