( | x | − | x | ÷ | 40 | ) | + | ( | x | − | 7875 | ) | = | 8200 | ÷ | 19 20 | + | 150 |
Left side of the equation = | x | − | x | ÷ | 40 | + | ( | x | − | 7875 | ) |
= | 39 40 | x | + | ( | x | − | 7875 | ) |
= | 39 40 | x | + | x | − | 7875 |
= | 79 40 | x | − | 7875 |
79 40 | x | − | 7875 | = | 8200 | ÷ | 19 20 | + | 150 |
Right side of the equation = | 164000 19 | + | 150 |
= | 166850 19 |
79 40 | x | − | 7875 | = | 166850 19 |
79 40 | x | = | 166850 19 | + | 7875 |
79 40 | x | = | 316475 19 |
x | = | 316475 19 | ÷ | 79 40 |
= | 316475 19 | × | 40 79 |
x | = | 12659000 1501 |
x | = | 8433.710859 |
