方程左边 = | x | − | 95 | + | ( | x | − | 102 | ) | + | ( | x | − | 100 | ) | + | ( | x | − | 99 | ) | + | ( | x | − | 104 | ) |
= | x | − | 95 | + | x | − | 102 | + | ( | x | − | 100 | ) | + | ( | x | − | 99 | ) | + | ( | x | − | 104 | ) |
= | 2 | x | − | 197 | + | ( | x | − | 100 | ) | + | ( | x | − | 99 | ) | + | ( | x | − | 104 | ) |
= | 2 | x | − | 197 | + | x | − | 100 | + | ( | x | − | 99 | ) | + | ( | x | − | 104 | ) |
= | 3 | x | − | 297 | + | ( | x | − | 99 | ) | + | ( | x | − | 104 | ) |
= | 3 | x | − | 297 | + | x | − | 99 | + | ( | x | − | 104 | ) |
= | 4 | x | − | 396 | + | ( | x | − | 104 | ) |
= | 4 | x | − | 396 | + | x | − | 104 |
= | 5 | x | − | 500 |
5 | x | − | 500 | = | x |
5 | x | − | x | = | 500 |
4 | x | = | 500 |
x | = | 500 | ÷ | 4 |
= | 500 | × | 1 4 |
= | 125 | × | 1 |
x | = | 125 |
