Question

12x - 4y = 20 , for y

Answer 1

Step 1: Simplify the equation by getting all variables with y on one side of the equal sign and all other variables on the other side of the equal sign

12x - 4y = 20

-12x -12x

You are left with

-4y = 20 - 12x

Step 2: Now get y completely by itself

-4y = 20 - 12x

-4 -4 -4

The fours on the left side of the equal sign cancel each other out, so we are left with

y = 20 - 12x

-4 -4

Now, divide 20 by -4 and -12 by -4

y = -5 + 3x

Answer 2

To solve for y, first get y by itself on one side of the equation.

-4y = -12x + 20

Next, we divide each side by (-4), to get y positive by itself. This leaves us with the solution for y:

y = 3x - 5
