Solve the following equation
2h+8=5h+2
Solve for h
2h + 8 = 5h + 2
Group variables
Group our variables 2h and 5h
subtract 5h from both sides
2h + 8 - 5h = 5h + 2 - 5h
Cancel 5h on the right side:
-3h + 8 = 2
Divide each side by 2
| 2h | |
| 2 |
| = |
| 8 |
| 2 |
Group constants
Group our constants 8 and 2.
subtract 8 from both sides
-3h + 8 - 8 = 2 - 8
Cancel 8 on the left side:
-3h = -6
Divide each side of the equation by -3
| -3h | |
| -3 |
| = |
| -6 |
| -3 |
h = 2
Final Answer
h = 2
