| ( | 2 | × | 19 20 | + | x | ) | × | 51 50 | = | 2 | + | x |
| Left side of the equation = | 2 | × | 19 20 | × | 51 50 | + | x | × | 51 50 |
| = | 969 500 | + | x | × | 51 50 |
969 500 | + | 51 50 | x | = | 2 | + | x |
51 50 | x | − | x | = | 2 | − | 969 500 |
1 50 | x | = | 2 | − | 969 500 |
1 50 | x | = | 31 500 |
| x | = | 31 500 | ÷ | 1 50 |
| = | 31 500 | × | 50 |
| = | 31 10 | × | 1 |
| x | = | 31 10 |
| x | = | 3.1 |
