Work: Find the solution of equation x*99.686*4.2-(100-x)*5.82*4.2 = 12027 .
Question type: Equation
Solution:Original question:
| x | × | 49843 500 | × | 21 5 | − | ( | 100 | − | x | ) | × | 291 50 | × | 21 5 | = | 12027 |
| Left side of the equation = | x | × | 1046703 2500 | − | ( | 100 | − | x | ) | × | 6111 250 |
1046703 2500 | x | − | ( | 100 | − | x | ) | × | 6111 250 | = | 12027 |
| Left side of the equation = | 1046703 2500 | x | − | 100 | × | 6111 250 | + | x | × | 6111 250 |
| = | 1046703 2500 | x | − | 12222 5 | + | x | × | 6111 250 |
| = | 1107813 2500 | x | − | 12222 5 |
1107813 2500 | x | − | 12222 5 | = | 12027 |
Transposition :
1107813 2500 | x | = | 12027 | + | 12222 5 |
Combine the items on the right of the equation:
1107813 2500 | x | = | 72357 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 72357 5 | ÷ | 1107813 2500 |
| = | 72357 5 | × | 2500 1107813 |
| = | 24119 | × | 500 369271 |
We obtained :
| x | = | 12059500 369271 |
Convert the result to decimal form :
| x | = | 32.657588 |
