X | − | ( | 500 | + | 600 | + | 3 10 | X | + | 1 2 | X | × | 1 5 | ) | = | 0 |
Left side of the equation = | X | − | 500 | − | 600 | − | 3 10 | X | − | 1 2 | X | × | 1 5 |
= | X | − | 500 | − | 600 | − | 3 10 | X | − | 1 10 | X |
= | 3 5 | X | − | 1100 |
3 5 | X | − | 1100 | = | 0 |
3 5 | X | = | 0 | + | 1100 |
3 5 | X | = | 1100 |
X | = | 1100 | ÷ | 3 5 |
= | 1100 | × | 5 3 |
X | = | 5500 3 |
X | = | 1833.333333 |
