Solve the following equation
12+2w=20
Solve for w
12 + 2w = 20
Divide each side by 12
| 12w | |
| 12 |
| = |
| 2 |
| 12 |
Group constants
Group our constants 12 and 20.
subtract 12 from both sides
2w + 12 - 12 = 20 - 12
Cancel 12 on the left side:
2w = 8
Divide each side of the equation by 2
| 2w | |
| 2 |
| = |
| 8 |
| 2 |
w = 4
Final Answer
w = 4
