a)
16x - 10x = 143 - 65
6x = 78
x = 78/6
x = 13
b)
-8x + 5x = -6
-3x = -6
x = -6/-3
x = 2
c)
3x + 2x + 5x = 12 * 50
10x = 600
x = 600/10
x = 60
d)
12x - 37 = 58 + 7x
12x - 7x = 58 + 37
5x = 95
x = 95/5
x = 19
e)
-9 + x = 3x - 35
x - 3x = -35 + 9
-2x = -26
x = -26/-2
x = 13
f)
6(7x - 5) = (6x + 3)8
42x - 30 = 48x + 24
42x - 48x = 24 + 30
-6x = 54
x = 54/-6
x = -9
g)
-2(3x - 8) = -12 - 13x
-6x + 16 = -12 - 13x
-6x + 13x = -12 - 16
7x = -28
x = -28/7
x = -4
