Solve the following equation
418-2s+6.50s=836.50
Solve for s
418 - 2s + 6.50s = 836.50
Group the s terms on the left:
(-2 + 6.5)s = 4.5s
Form modified equation
4.5s + 418 = + 836.5
Divide each side by 418
| 418s | |
| 418 |
| = |
| -2 |
| 418 |
Group constants
Group our constants 418 and 836.50.
subtract 418 from both sides
4.5s + 418 - 418 = 836.50 - 418
Cancel 418 on the left side:
4.5s = 418.5
Divide each side of the equation by 4.5
| 4.5s | |
| 4.5 |
| = |
| 418.5 |
| 4.5 |
s = 93
Final Answer
s = 93
