To solve for y, we need to isolate y on one side of the equation.
Given:
w = 1/3 (x + y - z)
First, multiply both sides by 3 to get rid of the fraction:
3w = x + y - z
Next, isolate y by moving x and z to the other side of the equation:
3w - x + z = y
Therefore, y = 3w - x + z.
w = 1/3 ( x + y - z) solve for y
