100 | × | 137 10 | + | x | × | 301 10 | = | ( | 100 | + | x | ) | × | 25 |
方程左边 = | 1370 | + | x | × | 301 10 |
1370 | + | 301 10 | x | = | ( | 100 | + | x | ) | × | 25 |
方程右边 = | 100 | × | 25 | + | x | × | 25 |
= | 2500 | + | x | × | 25 |
1370 | + | 301 10 | x | = | 2500 | + | 25 | x |
301 10 | x | − | 25 | x | = | 2500 | − | 1370 |
51 10 | x | = | 2500 | − | 1370 |
51 10 | x | = | 1130 |
x | = | 1130 | ÷ | 51 10 |
= | 1130 | × | 10 51 |
x | = | 11300 51 |
