| X | − | 1 5 | X | − | 1 20 | X | − | 2 | = | 143 10 | + | 1 5 | × | 143 10 |
| Left side of the equation = | 3 4 | X | − | 2 |
3 4 | X | − | 2 | = | 143 10 | + | 1 5 | × | 143 10 |
| Right side of the equation = | 143 10 | + | 143 50 |
| = | 429 25 |
3 4 | X | − | 2 | = | 429 25 |
3 4 | X | = | 429 25 | + | 2 |
3 4 | X | = | 479 25 |
| X | = | 479 25 | ÷ | 3 4 |
| = | 479 25 | × | 4 3 |
| X | = | 1916 75 |
