Simplify by combining similar terms, then solve:
5). 5X - 3X = 18
X = |
6). 2X + 6X - 3X = 30
X = |
7). 5X - 3X + 2 = 16
X = |
8). X + 2X + 13 - X - 8 = 21
X = |
Simplify by combining similar terms:
9). 7a +8b + 3a +4b =
|
10). 7a + 6b + 5c + 4a + 3b + 2c =
|
11). 4a +3b + 6a +9b =
|
12). 5x + 7y - 2x + 3y =
|
13). t + 4q - t + 8q =
|
14). 3a - 4a + b - 2b + 6b + a =
|
| 15). 4x2 + 3y - 4x + 2x2 - y + x= |
16). 3t3 + 2t2 - t3 - 6t2 = |
