Answer
q=13
↓Steps Explained:↓
Solve for q
0.3q + 0.3 = 4.2
Divide each side by 0.3
| 0.3q | |
| 0.3 |
| = |
| 0.3 |
| 0.3 |
Group constants
Group our constants 0.3 and 4.2.
subtract 0.3 from both sides
0.3q + 0.3 - 0.3 = 4.2 - 0.3
Cancel 0.3 on the left side:
0.3q = 3.9
Divide each side of the equation by 0.3
| 0.3q | |
| 0.3 |
| = |
| 3.9 |
| 0.3 |
q = 13
