方程右边 = | 5 | − | 95 4 | ( | x | − | 4 5 | ) |
x | = | 5 | − | 95 4 | ( | x | − | 4 5 | ) |
方程右边 = | 5 | − | 95 4 | x | + | 95 4 | × | 4 5 |
= | 5 | − | 95 4 | x | + | 19 |
= | 24 | − | 95 4 | x |
x | = | 24 | − | 95 4 | x |
x | + | 95 4 | x | = | 24 |
99 4 | x | = | 24 |
x | = | 24 | ÷ | 99 4 |
= | 24 | × | 4 99 |
= | 8 | × | 4 33 |
x | = | 32 33 |
