I need Help solving W(-4+z)=Mz+17 for z

Question

Please help me solve this because I can’t figure it out

Answer 1

w(-4 + z) = mz + 17

You need to get z by itself on one side of the equation. Start by expanding the parenthesis.

-4w + wz = mz + 17

Add 4w to both sides and get

wz = mz + 17 + 4w

Subtract mz from both sides and get

wz - mz = 17 + 4w

Group the terms on the left and get

(w - m)z = 17 + 4w

Divide both sides by (w - m) and get

z = (17 + 4w) / (w - m)
