400 | × | 643 10 | − | 400 | t | = | 150 | × | 1653 10 | − | 150 | t |
方程左边 = | 25720 | − | 400 | t |
25720 | − | 400 | t | = | 150 | × | 1653 10 | − | 150 | t |
方程右边 = | 24795 | − | 150 | t |
25720 | − | 400 | t | = | 24795 | − | 150 | t |
- | 400 | t | + | 150 | t | = | 24795 | − | 25720 |
- | 250 | t | = | 24795 | − | 25720 |
- | 250 | t | = | - | 925 |
925 | = | 250 | t |
250 | t | = | 925 |
t | = | 925 | ÷ | 250 |
= | 925 | × | 1 250 |
= | 37 | × | 1 10 |
t | = | 37 10 |
t | = | 3.7 |
