Work: Find the solution of equation 2405*56.2%*1.25*0.8*0.5*（794+x-18） = 466 .
Question type: Equation
Solution:Original question:
| 2405 | × | 281 500 | × | 5 4 | × | 4 5 | × | 1 2 | ( | 794 | + | x | − | 18 | ) | = | 466 |
| Left side of the equation = | 135161 200 | ( | 794 | + | x | − | 18 | ) |
135161 200 | ( | 794 | + | x | − | 18 | ) | = | 466 |
| Left side of the equation = | 135161 200 | × | 794 | + | 135161 200 | x | − | 135161 200 | × | 18 |
| = | 53658917 100 | + | 135161 200 | x | − | 1216449 100 |
| = | 13110617 25 | + | 135161 200 | x |
13110617 25 | + | 135161 200 | x | = | 466 |
Transposition :
135161 200 | x | = | 466 | − | 13110617 25 |
Combine the items on the right of the equation:
135161 200 | x | = | - | 13098967 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 13098967 25 | ÷ | 135161 200 |
| = | - | 13098967 25 | × | 200 135161 |
| = | - | 13098967 | × | 8 135161 |
We obtained :
| x | = | - | 104791736 135161 |
Convert the result to decimal form :
| x | = | - 775.310452 |
