Answer:
x=-1
Step-by-step explanation:
9(x+2) = 5 - 2(x - 1)
9x+18 = 5-2x+2
9x+18 = -2x+7
+2x = +2x +7
-----------------------
11x+18 = 7
-18 = -18
-----------------------
11x = -11
÷11 = ÷11
-----------------------
x = -1
Answer:
x = -1
Step-by-step explanation:
9(x+2) = 5 - 2(x-1)
9(x+2) = 5 - 2(x - 1)
9x+18 = 5-2x+2
9x+18 = -2x+7
+2x +2x
11x + 18 = 7
-7 -7
11x + 11 = 0
-11 -11
11x = -11
x = -1
