-21 = 9a - 15 - 3a -6 = 6a -1 = a

-14 + 9a = 389a = 52a = 52/9 or 5.78

a= -0.8

a is equal to 1.

a= -4

9a + 4a = 26 13a = 26 a = 26/13 a = 2

Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3

4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5

a + 3a + 5a = 180 9a =180 a = 20

It is: 9a-a-a = 7a
