1768 5 | + | 637 5 | x | = | 77 | ( | x | + | 37 10 | ) |
| Right side of the equation = | 77 | x | + | 77 | × | 37 10 |
| = | 77 | x | + | 2849 10 |
1768 5 | + | 637 5 | x | = | 77 | x | + | 2849 10 |
637 5 | x | − | 77 | x | = | 2849 10 | − | 1768 5 |
252 5 | x | = | 2849 10 | − | 1768 5 |
252 5 | x | = | - | 687 10 |
| x | = | - | 687 10 | ÷ | 252 5 |
| = | - | 687 10 | × | 5 252 |
| = | - | 229 2 | × | 1 84 |
| x | = | - | 229 168 |
| x | = | - 1.363095 |
