Solve the following equation
39d+295=33d+320
Solve for d
39d + 295 = 33d + 320
Group variables
Group our variables 39d and 33d
subtract 33d from both sides
39d + 295 - 33d = 33d + 320 - 33d
Cancel 33d on the right side:
6d + 295 = 320
Divide each side by 39
| 39d | |
| 39 |
| = |
| 295 |
| 39 |
Group constants
Group our constants 295 and 320.
subtract 295 from both sides
6d + 295 - 295 = 320 - 295
Cancel 295 on the left side:
6d = 25
Divide each side of the equation by 6
| 6d | |
| 6 |
| = |
| 25 |
| 6 |
d = 4.1666666666667
Final Answer
d = 4.1666666666667
