1 2 | y | ÷ | 60 | + | 30 | × | 5 | + | 15 | × | 1 | ÷ | 2 | − | 6 | y | = | 6 | y | − | 3 | × | 30 | − | 6 | y | ÷ | 60 |
方程左边 = | 1 120 | y | + | 150 | + | 15 2 | − | 6 | y |
= | - | 719 120 | y | + | 315 2 |
- | 719 120 | y | + | 315 2 | = | 6 | y | − | 3 | × | 30 | − | 6 | y | ÷ | 60 |
方程右边 = | 6 | y | − | 90 | − | 1 10 | y |
= | 59 10 | y | − | 90 |
- | 719 120 | y | + | 315 2 | = | 59 10 | y | − | 90 |
- | 719 120 | y | − | 59 10 | y | = | - | 90 | − | 315 2 |
- | 1427 120 | y | = | - | 90 | − | 315 2 |
- | 1427 120 | y | = | - | 495 2 |
495 2 | = | 1427 120 | y |
1427 120 | y | = | 495 2 |
y | = | 495 2 | ÷ | 1427 120 |
= | 495 2 | × | 120 1427 |
= | 495 | × | 60 1427 |
y | = | 29700 1427 |
y | = | 20.812894 |
