Answer: 20-2x/-4

Step-by-step explanation:

To actually solve for y as a number, you need two equations.

For this case move the 2x to the other side, making the equation -4y=20-2x.

Then divide by -4 on each side making the equation y=20-2x/-4.

Answer:

y = 20-2x /-4

Step-by-step explanation:

Given 2x - 4y =20

y ?

Subtract 2x from both sides of the equation

2x - 2x -4y = 20 - 2x

-4y = 20 - 2x

Divide both sides by -4

-4y/-4 = 20-2x / -4

y = 20-2x /-4
