Simplify by combining similar terms then find X in each of these equations:
5). X + X + X = 18
6). 3X - 2X = 15
7). 5X + 2X + 2X = 81
8). X + 5 - 3 = 10
9). 2X

= 81
10). X + X + X + X + X = 30
Simplify by combining similar terms:
11). 5a + 2b + 5a + 4b =
12). 6a + 3b + 4c + 2a + 3b + 5c =
13). x + 5y - 2x + 16y =
14). 4a - 3b + 2a - 6b=
