Solve the following equation
0.8m-0.4=20.75
Solve for m
0.8m - 0.4 = 20.75
Divide each side by 0.8
| 0.8m | |
| 0.8 |
| = |
| -0.4 |
| 0.8 |
Group constants
Group our constants -0.4 and 20.75.
add 0.4 to both sides
0.8m - 0.4 + 0.4 = 20.75 + 0.4
Cancel 0.4 on the left side:
0.8m = 21.15
Divide each side of the equation by 0.8
| 0.8m | |
| 0.8 |
| = |
| 21.15 |
| 0.8 |
m = 26.4375
Final Answer
m = 26.4375
