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

Add '-4y' to each side of the equation.
32 + -4y = 4y + -4y

Combine like terms: 4y + -4y = 0
32 + -4y = 0

Add '-32' to each side of the equation.
32 + -32 + -4y = 0 + -32

Combine like terms: 32 + -32 = 0
0 + -4y = 0 + -32
-4y = 0 + -32

Combine like terms: 0 + -32 = -32
-4y = -32

Divide each side by '-4'.
y = 8

Simplifying
y = 8
