| Solve for x: | 5(x + 3) = 3x + 23. | |
| Simplify by distributing: | 5x + 15 = 3x + 23. | |
| Subtract 3x from both sides: | 5x + 15 - 3x = 3x + 23 - 3x. | |
| Simplify: | 2x + 15 = 23. | |
| Subtract 15 from both sides: | 2x + 15 - 15 = 23 - 15. | |
| Simplify: | 2x = 8. | |
| Divide both sides by 2: | 2x/2 = 8/2. | |
| Simplify: | x = 4. |
