| ( | 5 | x | + | 136 | ) | ÷ | ( | 3 | x | + | 136 | ) | = | 11 | ÷ | 10 |
| Multiply both sides of the equation by: | ( | 3 | x | + | 136 | ) |
| ( | 5 | x | + | 136 | ) | = | 11 | ÷ | 10 | × | ( | 3 | x | + | 136 | ) |
| 5 | x | + | 136 | = | 11 | ÷ | 10 | × | ( | 3 | x | + | 136 | ) |
| 5 | x | + | 136 | = | 11 | ÷ | 10 | × | 3 | x | + | 11 | ÷ | 10 | × | 136 |
| 5 | x | + | 136 | = | 33 10 | x | + | 748 5 |
| 5 | x | − | 33 10 | x | = | 748 5 | − | 136 |
17 10 | x | = | 748 5 | − | 136 |
17 10 | x | = | 68 5 |
| x | = | 68 5 | ÷ | 17 10 |
| = | 68 5 | × | 10 17 |
| = | 4 | × | 2 |
| x | = | 8 |
