Solve the following equation
9079+19d=9259+d
Solve for d
9079 + 19d = 9259 + d
Group variables
Group our variables 19d and d
subtract d from both sides
19d + 9079 - d = d + 9259 - d
Cancel d on the right side:
18d + 9079 = 9259
Divide each side by 9079
| 9079d | |
| 9079 |
| = |
| 19 |
| 9079 |
Group constants
Group our constants 9079 and 9259.
subtract 9079 from both sides
18d + 9079 - 9079 = 9259 - 9079
Cancel 9079 on the left side:
18d = 180
Divide each side of the equation by 18
| 18d | |
| 18 |
| = |
| 180 |
| 18 |
d = 10
Final Answer
d = 10
