Answer:
8 = m, No solution
Step-by-step explanation:
1. -88 = -3(4m + 5) - (1 - 3m)
-88 = -12m - 15 - 1 + 3m : distributed into parentheses
-88 = -9m - 16 : combined like terms
+16 + 16 : adding to cancel out
-72 = -9m
/-9 /-9 : dividing by -9 to cancel
8 = m
2. -4(5k - 7) + 2k = -2(9k + 5)
-20k + 28 + 2k = -18k - 10 : distributed into parentheses
-18k + 28 = -18k - 10 : combined like terms
+ 10 + 10 : adding to cancel out
-18k + 38 = -18k
+18k +18k : adding to cancel out
38 = 0k (No solution)
