Work: Find the solution of equation X/1000+（74.4-X）/1650+20/133.58 = 0.226 .
Question type: Equation
Solution:Original question:
| X | ÷ | 1000 | + | ( | 372 5 | − | X | ) | ÷ | 1650 | + | 20 | ÷ | 6679 50 | = | 113 500 |
| Left side of the equation = | X | × | 1 1000 | + | ( | 372 5 | − | X | ) | × | 1 1650 | + | 1000 6679 |
1 1000 | X | + | ( | 372 5 | − | X | ) | × | 1 1650 | + | 1000 6679 | = | 113 500 |
| Left side of the equation = | 1 1000 | X | + | 372 5 | × | 1 1650 | − | X | × | 1 1650 | + | 1000 6679 |
| = | 1 1000 | X | + | 62 1375 | − | X | × | 1 1650 | + | 1000 6679 |
| = | 13 33000 | X | + | 1789098 9183625 |
13 33000 | X | + | 1789098 9183625 | = | 113 500 |
Transposition :
13 33000 | X | = | 113 500 | − | 1789098 9183625 |
Combine the items on the right of the equation:
13 33000 | X | = | 229121 7346900 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 229121 7346900 | ÷ | 13 33000 |
| = | 229121 7346900 | × | 33000 13 |
| = | 229121 6679 | × | 30 13 |
We obtained :
| X | = | 6873630 86827 |
Convert the result to decimal form :
| X | = | 79.164661 |
