1 | y | − | ( | 1 | y | ÷ | 113 100 | × | 13 100 | − | 1 | × | 50 | ) | × | 11 10 | − | 950 | = | 0 |
方程左边 = | 1 | y | − | 1 | y | ÷ | 113 100 | × | 13 100 | × | 11 10 | + | 1 | × | 50 | × | 11 10 | − | 950 |
= | 1 | y | − | 143 1130 | y | + | 55 | − | 950 |
= | 987 1130 | y | − | 895 |
987 1130 | y | − | 895 | = | 0 |
987 1130 | y | = | 0 | + | 895 |
987 1130 | y | = | 895 |
y | = | 895 | ÷ | 987 1130 |
= | 895 | × | 1130 987 |
y | = | 1011350 987 |
