### Subject: Algebra

Question:

Solve -16x + 4y + 16 = 0 for y.

Inactive

Justin R.

Answer:

The goal is to isolate y by itself on one side of the equation: 1) Add 16x to both sides: equation becomes 4y + 16 = 16x 2) Subtract 16 from both sides: equation becomes 4y = 16x - 16 3) Divide 4 from both sides: equation becomes y = (16x - 16) / 4 4) Simplify equation: solution becomes y = 4x - 4
