Solve the following equation
38h+150=30h+230
Solve for h
38h + 150 = 30h + 230
Group variables
Group our variables 38h and 30h
subtract 30h from both sides
38h + 150 - 30h = 30h + 230 - 30h
Cancel 30h on the right side:
8h + 150 = 230
Divide each side by 38
| 38h | |
| 38 |
| = |
| 150 |
| 38 |
Group constants
Group our constants 150 and 230.
subtract 150 from both sides
8h + 150 - 150 = 230 - 150
Cancel 150 on the left side:
8h = 80
Divide each side of the equation by 8
| 8h | |
| 8 |
| = |
| 80 |
| 8 |
h = 10
Final Answer
h = 10
