16. 7x = 2(x-3)
7x = 2x – 6
(now put all like terms on one side – by subtracting 2x from each side)
5x = 6
(now solve for x by dividing 6 by 5)
x = 6/5
the rest are no different
18. 5(x+.5) = -1.5(x+3x)
5x + 2.5 = -1.5x – 4.5x
5x + 2.5 = -6x
2.5 = – 11x
x = 2.5/11 or x = 25/110
20. 2x = 3(x + 2)
2x = 3x + 6
-x = 6
x = -6
22. 2x + 2(2x-3) = -3
2x + 4x – 6 = -3
6x = 9
x = 9/6
x = 3/2 or x = 1 and 1/2
