Solve

W=3y + 3z, for y

W = 3y+3z, for z

w = 3y + 3z Subtract 3z from both sides

w - 3z = 3y Divide both sides by 3

w - 3z / 3 = y Switch the sides to make it easier to read

y = w - 3z / 3

w = 3y + 3z Subtract 3y from both sides

w - 3y = 3z Divide both sides by 3

w - 3y / 3 = z Switch the sides to make it easier to read

z = w - 3y / 3
