Solve the following equation
2w+50=120
Solve for w
2w + 50 = 120
Divide each side by 2
| 2w | |
| 2 |
| = |
| 50 |
| 2 |
Group constants
Group our constants 50 and 120.
subtract 50 from both sides
2w + 50 - 50 = 120 - 50
Cancel 50 on the left side:
2w = 70
Divide each side of the equation by 2
| 2w | |
| 2 |
| = |
| 70 |
| 2 |
w = 35
Final Answer
w = 35
