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
