Answer
a=624
Steps Explained:
Solve for a
6a + 4a + 120 = 6360
Group the a terms on the left:
(6 + 4)a = 10a
Form modified equation
10a + 120 = + 6360
Divide each side by 6
| 6a | |
| 6 |
| = |
| 4 |
| 6 |
Group constants
Group our constants 120 and 6360.
subtract 120 from both sides
10a + 120 - 120 = 6360 - 120
Cancel 120 on the left side:
10a = 6240
Divide each side of the equation by 10
| 10a | |
| 10 |
| = |
| 6240 |
| 10 |
a = 624
