Answer
h=2
↓Steps Explained:↓
Solve for h
15h + 20 = 5h + 40
Group variables
Group our variables 15h and 5h
subtract 5h from both sides
15h + 20 - 5h = 5h + 40 - 5h
Cancel 5h on the right side:
10h + 20 = 40
Divide each side by 15
| 15h | |
| 15 |
| = |
| 20 |
| 15 |
Group constants
Group our constants 20 and 40.
subtract 20 from both sides
10h + 20 - 20 = 40 - 20
Cancel 20 on the left side:
10h = 20
Divide each side of the equation by 10
| 10h | |
| 10 |
| = |
| 20 |
| 10 |
h = 2
