Question

Solve for y.

48 = 3y-12

Simplify as much as possible

Answer 1

y=20

Explanation:

Move all terms containing y to the left, all other terms to the right.

Add -3y to each side of the equation.

48 + -3y = -12 + 3y + -3y

Combine like terms: 3y + -3y = 0

48 + -3y = -12 + 0

48 + -3y = -12

Add -48 to each side of the equation.

48 + -48 + -3y = -12 + -48

Combine like terms: 48 + -48 = 0

0 + -3y = -12 + -48

-3y = -12 + -48

Combine like terms: -12 + -48 = -60

-3y = -60

Divide each side by -3.

y = 20

Simplifying

y = 20

Answer 2

y = 20

Explanation:

48 = 3y - 12

Divide by 3 to have one "y'

16 = y - 4

Add 4 to isolate variable

20 = y

So y is equal to 20.
