Solve the following equation
10-f+1.5f=12.50
Solve for f
10 - f + 1.5f = 12.50
Group the f terms on the left:
(-1 + 1.5)f = 0.5f
Form modified equation
0.5f + 10 = + 12.5
Divide each side by 10
| 10f | |
| 10 |
| = |
| 1.5 |
| 10 |
Group constants
Group our constants 10 and 12.50.
subtract 10 from both sides
0.5f + 10 - 10 = 12.50 - 10
Cancel 10 on the left side:
0.5f = 2.5
Divide each side of the equation by 0.5
| 0.5f | |
| 0.5 |
| = |
| 2.5 |
| 0.5 |
f = 5
Final Answer
f = 5
