y = -32 6y + 22 = 4y - 42 subtract -4y from both sides 2y + 22 = -42 subtract 22 from both sides 2y = -64 Divide both sides by 2 to get y by itself y= -32
x=7 y=4
Y=5
18+y=32 y=14
y=84-72=12 z=84-52=32 x=84-12-32=40

54(x)+52+32(y)+72=212
If -y = -32, then y = 32.
-2-5
You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
