x | − | ( | x | ÷ | 21 20 | × | 1 20 | + | x | ÷ | 21 20 | × | 1 20 | × | 3 25 | ) | = | 300000 |
Left side of the equation = | x | − | x | ÷ | 21 20 | × | 1 20 | − | x | ÷ | 21 20 | × | 1 20 | × | 3 25 |
= | x | − | x | × | 1 21 | − | x | × | 1 175 |
= | 71 75 | x |
71 75 | x | = | 300000 |
x | = | 300000 | ÷ | 71 75 |
= | 300000 | × | 75 71 |
x | = | 22500000 71 |
x | = | 316901.408451 |
