Answer: y = 12x − 9

Step-by-step explanation:

Let's solve for y

-1/3y +4x = 3

Step 1: Add -4x to both sides.

4x + -1/3y + -4x = 3 + -4x
-1/3y = -4x+3

Step 2: Divide both sides by (-1)/3.

-1/3y / -1/3 = -4x+3 / -1/3
y = 12 - 9
1. Simplify
-y/3+4x=3
2. Regroup terms
4x-y/3=3
3. Subtract 4x from both sides
-y/3 =3-4x
4. Multiply both sides by 3
-y=(3-4x)•3
5. Regroup terms
-y=3(3-4x)
6. Multiply both sides by -1
y=-3(3-4x)
