**Jennifer**, Wednesday, January 30, 2013 at 8:24pmI imagine you're supposed to solve for the missing variables. I'll do a couple so you get the idea.

1)

2a - a/5 = 2/3

adding like terms:

1.8 a = 2/3

9/5 a = 2/3

a = 10/27

2)

3(a+4)+1 = a/2

3*a + 12 + 1 = a/2

3*a + 13 = a/2

13 = -2.5a

a = 13/-2.5

. . .
