Solve the following equation
400-2a=244
Solve for a
400 - 2a = 244
Divide each side by 400
| 400a | |
| 400 |
| = |
| -2 |
| 400 |
Group constants
Group our constants 400 and 244.
subtract 400 from both sides
-2a + 400 - 400 = 244 - 400
Cancel 400 on the left side:
-2a = -156
Divide each side of the equation by -2
| -2a | |
| -2 |
| = |
| -156 |
| -2 |
a = 78
Final Answer
a = 78
