500 | × | 5 | = | X | − | 500 | − | ( | 300 | + | 500 | × | 5 100 | ) | × | 5 |
Left side of the equation = | 2500 |
2500 | = | X | − | 500 | − | ( | 300 | + | 500 | × | 5 100 | ) | × | 5 |
Right side of the equation = | X | − | 500 | − | 300 | × | 5 | − | 500 | × | 5 100 | × | 5 |
= | X | − | 500 | − | 1500 | − | 125 |
= | X | − | 2125 |
2500 | = | X | − | 2125 |
- | X | = | - | 2125 | − | 2500 |
- | X | = | - | 4625 |
4625 | = | X |
X | = | 4625 |
