x | = | 4 | ÷ | 15 | × | ( | 28 | ÷ | 5 | − | x | ) |
方程右边 = | 4 15 | ( | 28 | ÷ | 5 | − | x | ) |
x | = | 4 15 | ( | 28 | ÷ | 5 | − | x | ) |
方程右边 = | 4 15 | × | 28 | ÷ | 5 | − | 4 15 | x |
= | 112 75 | − | 4 15 | x |
x | = | 112 75 | − | 4 15 | x |
x | + | 4 15 | x | = | 112 75 |
19 15 | x | = | 112 75 |
x | = | 112 75 | ÷ | 19 15 |
= | 112 75 | × | 15 19 |
= | 112 5 | × | 1 19 |
x | = | 112 95 |
x | = | 1.178947 |
