2x + y = z
WHEN SOLVING FOR X :
2x + y = z
We just need to isolate x, so subtract y from both sides.
2x = -y + z
Then, divide both sides by 2.
2x ÷ 2 = -y + z ÷ 2
Simplify.
x = -y + z / 2 →
WHEN SOLVING FOR Y :
2x + y = x
We need to isolate y, so subtract 2x from both sides.
y = x - 2x
Simplify.
y = -x
