x | − | ( | 57 100 | x | + | 12000 | + | 12000 | + | 4000 | ) | = | 0 |
Left side of the equation = | x | − | 57 100 | x | − | 12000 | − | 12000 | − | 4000 |
= | 43 100 | x | − | 28000 |
43 100 | x | − | 28000 | = | 0 |
43 100 | x | = | 0 | + | 28000 |
43 100 | x | = | 28000 |
x | = | 28000 | ÷ | 43 100 |
= | 28000 | × | 100 43 |
x | = | 2800000 43 |
x | = | 65116.27907 |
