x | − | ( | ( | x | − | 8664 | − | 60000 | ) | × | 10 100 | − | 2520 | ) | = | 84000 |
Left side of the equation = | x | − | ( | x | − | 8664 | − | 60000 | ) | × | 10 100 | + | 2520 |
= | x | − | x | × | 10 100 | + | 8664 | × | 10 100 | + | 60000 | × | 10 100 | + | 2520 |
= | x | − | x | × | 10 100 | + | 4332 5 | + | 6000 | + | 2520 |
= | 9 10 | x | + | 46932 5 |
9 10 | x | + | 46932 5 | = | 84000 |
9 10 | x | = | 84000 | − | 46932 5 |
9 10 | x | = | 373068 5 |
x | = | 373068 5 | ÷ | 9 10 |
= | 373068 5 | × | 10 9 |
= | 41452 | × | 2 |
x | = | 82904 |
