Work: Find the solution of equation x = 11000-200-1201（x*0.21+212）-（x*0.2+424）-550 .
Question type: Equation
Solution:Original question:
| x | = | 11000 | − | 200 | − | 1201 | ( | x | × | 21 100 | + | 212 | ) | − | ( | x | × | 1 5 | + | 424 | ) | − | 550 |
| Right side of the equation = | 10250 | − | 1201 | ( | x | × | 21 100 | + | 212 | ) | − | ( | x | × | 1 5 | + | 424 | ) |
| x | = | 10250 | − | 1201 | ( | x | × | 21 100 | + | 212 | ) | − | ( | x | × | 1 5 | + | 424 | ) |
| Right side of the equation = | 10250 | − | 1201 | x | × | 21 100 | − | 1201 | × | 212 | − | ( | x | × | 1 5 | + | 424 | ) |
| = | 10250 | − | 25221 100 | x | − | 254612 | − | ( | x | × | 1 5 | + | 424 | ) |
| = | - | 244362 | − | 25221 100 | x | − | ( | x | × | 1 5 | + | 424 | ) |
| = | - | 244362 | − | 25221 100 | x | − | x | × | 1 5 | − | 424 |
| = | - | 244786 | − | 25241 100 | x |
| x | = | - | 244786 | − | 25241 100 | x |
Transposition :
| x | + | 25241 100 | x | = | - | 244786 |
Combine the items on the left of the equation:
25341 100 | x | = | - | 244786 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 244786 | ÷ | 25341 100 |
| = | - | 244786 | × | 100 25341 |
We obtained :
| x | = | - | 24478600 25341 |
Convert the result to decimal form :
| x | = | - 965.968194 |
