Solve the following equation
7u+25500=10u
Solve for u
7u + 25500 = 10u
Group variables
Group our variables 7u and 10u
subtract 10u from both sides
7u + 25500 - 10u = 10u - 10u
Cancel 10u on the right side:
-3u + 25500 = 0
Divide each side by 7
| 7u | |
| 7 |
| = |
| 25500 |
| 7 |
Group constants
Group our constants 25500 and 0.
subtract 25500 from both sides
-3u + 25500 - 25500 = 0 - 25500
Cancel 25500 on the left side:
-3u = -25500
Divide each side of the equation by -3
| -3u | |
| -3 |
| = |
| -25500 |
| -3 |
u = 8500
Final Answer
u = 8500
