Examples:
 2x + 8 = 14 Then x = ?
2x + 8 = 14 subtracting 8 from both sides
2x + 8  8 = 14  8
2x = 6 Dividing both sides by 2
2x/2 = 6/2
x = 3
 6y  15 = 2y + 9 Then y = ?
6y  15 = 2y + 9 subtracting 2y from both sides
6y  15  2y = 2y + 9  2y
4y  15 = 9 Adding 15 both sides
4y  15 + 15 = 9 + 15
4y = 24 dividing both sides by 4
4y/4 = 24/4
y = 6
 4(s + 1) = 2(4  s) distributive property
Note: Negative number multiplied by a negative number is positive. 2 x s = 2s
4s + 4 = 8 + 2s subtracting 2s both sides
4s + 4  2s= 8 + 2s  2s
2s + 4 = 8 subtracting 4 both sides
2s + 4  4 = 8  4
2s =  12 dividing both sides by 2
2s/2 =  12/2
s = 6
 2/x = 3/6
x/2 = 6/3
x/2 = 2
x = 4
 t/6 + 2 = t/3
This equation contains fractions so multiply both sides by the LCD of 6 and 3 that is 6
6(t/6 + 2) = 6(t/3)
t + 12 = 2t subtracting t from both sides
t + 12  t = 2t  t
12 = t
Therefore, t = 12
