| Solve 4x + 3 = 19 |
Reason: |
| 4x + 3 - 3 = 19 - 3 |
The objective is to find x. First remove + 3 from the left. Subtract 3 from both sides. |
| 4x = 16 |
Calculate the left. Calculate the right. |
 |
Next remove the 4 in front of the x from the left. Divide both sides by 4. |
| x = 4 |
Calculate the left. Calculate the right. |
