x | − | ( | ( | x | − | 5000 | ) | × | 1 10 | − | 210 | ) | = | 0 |
Left side of the equation = | x | − | ( | x | − | 5000 | ) | × | 1 10 | + | 210 |
= | x | − | x | × | 1 10 | + | 5000 | × | 1 10 | + | 210 |
= | x | − | x | × | 1 10 | + | 500 | + | 210 |
= | 9 10 | x | + | 710 |
9 10 | x | + | 710 | = | 0 |
9 10 | x | = | 0 | − | 710 |
9 10 | x | = | - | 710 |
x | = | - | 710 | ÷ | 9 10 |
= | - | 710 | × | 10 9 |
x | = | - | 7100 9 |
x | = | - 788.888889 |
