4(4m -3) + -1m(m + -5) = -52
4(-3 + 4m) + -1(m + -5) = -52
(-3 * 4 + 4m * 4) + -1(m + -5) = -52
(-12 + 16m) + -1(m + -5) = -52
-12 + 16m + -1(-5 + m) = -52
-12 + 16m + (-5 * -1 + m * -1) = -52
-12 + 16m + (5 + -1m) = -52
-12 + 5 + 16m + -1m = -52
-12 + 5 = -7
-7 + 16m + -1m = -52
16m + -1m = 15m
-7 + 15m = -52
-7 + 15m = -52
-7 + 7 + 15m = -52 + 7
-7 + 7 = 0
0 + 15m = -52 + 7
15m = -52 + 7
-52 + 7 = -45
15m = -45
15m ÷ 15 = -45 ÷ 15
m = -3
m = -3
