To find the solution of the equation 7a - 12 = 30, we can create a table with different values for a and compute the corresponding values of the equation. Let's start by assuming a few values for a:
| a | 7a - 12 |
|---|---------|
| 0 | -12 |
| 5 | 23 |
| 7 | 37 |
| 9 | 53 |
|12 | 72 |
|15 | 93 |
|18 | 114 |
|20 | 128 |
As we can see from the table, when a = 18, the equation 7a - 12 equals 30. Thus, the solution to the equation is a = 18.
Use a table to find the solution of the equation.
7a - 12 = 30
