4(e + 3) -11 (e - 7) = 4 (e - 7) = 4 (5e + 2)
4e + 12 - 11e + 77 = 20e + 8
-7e + 89 = 20e + 8
-7e - 20e = 8 - 89
-27e = -81
e = 3
4(x + 3) = 6 (x - 1)
4x + 12 = 6x - 6
-2x = -18
x = 9
7(m + 3) = 45 - 3 (12 - m)
7m + 21 = 45 - 36 + 3m
7m + 21 = 9 + 3m
7m - 3m = 9 - 21
4m = - 12
m = -3
4(n - 1) + 5 (n + 1) = 100
4n - 4 + 5n + 5 = 100
9n + 1 = 100
9n = 100 - 1
9n = 99
n = 11
