Work: Find the solution of equation （y+800-2500-5213.15-4455.78）*（1-0.25）/（100000*0.3*0.9） = 0 .
Question type: Equation
Solution:Original question:
| ( | y | + | 800 | − | 2500 | − | 104263 20 | − | 222789 50 | ) | ( | 1 | − | 1 4 | ) | ÷ | ( | 100000 | × | 3 10 | × | 9 10 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 100000 | × | 3 10 | × | 9 10 | ) |
| ( | y | + | 800 | − | 2500 | − | 104263 20 | − | 222789 50 | ) | ( | 1 | − | 1 4 | ) | = | 0 |

3 4 | y | − | 414789 80 | − | 222789 50 | × | 1 | + | 222789 50 | × | 1 4 | = | 0 |
3 4 | y | − | 414789 80 | − | 222789 50 | + | 222789 200 | = | 0 |
3 4 | y | − | 3410679 400 | = | 0 |
Transposition :
3 4 | y | = | 0 | + | 3410679 400 |
Combine the items on the right of the equation:
3 4 | y | = | 3410679 400 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 3410679 400 | ÷ | 3 4 |
| = | 3410679 400 | × | 4 3 |
| = | 1136893 100 | × | 1 |
We obtained :
| y | = | 1136893 100 |
Convert the result to decimal form :
| y | = | 11368.93 |
