[ 1/1 Equation]
Work: Find the solution of equation 10000y/1.13-（10000y/1.13*0.13-50*10000)*0.1-400*10000-550*10000 = 0 .
Question type: Equation
Solution:Original question:
| 10000 | y | ÷ | 113 100 | − | ( | 10000 | y | ÷ | 113 100 | × | 13 100 | − | 50 | × | 10000 | ) | × | 1 10 | − | 400 | × | 10000 | − | 550 | × | 10000 | = | 0 |
| Left side of the equation = | 1000000 113 | y | − | ( | 10000 | y | ÷ | 113 100 | × | 13 100 | − | 50 | × | 10000 | ) | × | 1 10 | − | 4000000 | − | 5500000 |
| = | 1000000 113 | y | − | ( | 10000 | y | ÷ | 113 100 | × | 13 100 | − | 50 | × | 10000 | ) | × | 1 10 | − | 9500000 |
1000000 113 | y | − | ( | 10000 | y | ÷ | 113 100 | × | 13 100 | − | 50 | × | 10000 | ) | × | 1 10 | − | 9500000 | = | 0 |
| Left side of the equation = | 1000000 113 | y | − | 10000 | y | ÷ | 113 100 | × | 13 100 | × | 1 10 | + | 50 | × | 10000 | × | 1 10 | − | 9500000 |
| = | 1000000 113 | y | − | 13000 113 | y | + | 50000 | − | 9500000 |
| = | 987000 113 | y | − | 9450000 |
987000 113 | y | − | 9450000 | = | 0 |
Transposition :
987000 113 | y | = | 0 | + | 9450000 |
Combine the items on the right of the equation:
987000 113 | y | = | 9450000 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 9450000 | ÷ | 987000 113 |
| = | 9450000 | × | 113 987000 |
| = | 450 | × | 113 47 |
We obtained :
| y | = | 50850 47 |
Convert the result to decimal form :
| y | = | 1081.914894 |
