2 + 14z = -8 + 9zSubtract 9z from each side:2 + 5z = -8Subtract 2 from each side:5z = -10Divide each side by 5:z = -2
40
first add 12 plus 12 equals 24, then add 4 plus 4 and that equals 8. 24 plus 8 equals 32. 12 + 12 = 24 4 +4 =8 24 + 8 =32
-12
I'll do ya one better - 12 plus 8 equals what?

4 + 8 = 12 is correct.
