Is grade 9 homework
justify each step 24-X=-16 and -8=2X-5 and X/7+4=15
#1:
24 - x = -16
-24 -24
-x = -40 **
-1 -1
x = 40 ** Should be -40 **
Nicole's other answers look correct to me.
#1:
24 - x = -16
-24 -24
-x = -30
-1 -1
x = 30
#2:
-8 = 2x - 5
+5 +5
-3 = 2x
2 2
-3/2 = x
#3:
(x/7) + 4 = 15
- 4 - 4
(x/7) = 11
7 · x = 11 · 7
7
x = 77
