Work: Find the solution of equation 450X-（240X+310.2）-(450X*0.13-15X-30.4)*12% = 0 .
Question type: Equation
Solution:Original question:
| 450 | X | − | ( | 240 | X | + | 1551 5 | ) | − | ( | 450 | X | × | 13 100 | − | 15 | X | − | 152 5 | ) | × | 12 100 | = | 0 |
| Left side of the equation = | 450 | X | − | 240 | X | − | 1551 5 | − | ( | 450 | X | × | 13 100 | − | 15 | X | − | 152 5 | ) | × | 12 100 |
| = | 210 | X | − | 1551 5 | − | ( | 450 | X | × | 13 100 | − | 15 | X | − | 152 5 | ) | × | 12 100 |
| = | 210 | X | − | 1551 5 | − | 450 | X | × | 13 100 | × | 12 100 | + | 15 | X | × | 12 100 | + | 152 5 | × | 12 100 |
| = | 210 | X | − | 1551 5 | − | 351 50 | X | + | 9 5 | X | + | 456 125 |
| = | 10239 50 | X | − | 38319 125 |
10239 50 | X | − | 38319 125 | = | 0 |
Transposition :
10239 50 | X | = | 0 | + | 38319 125 |
Combine the items on the right of the equation:
10239 50 | X | = | 38319 125 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 38319 125 | ÷ | 10239 50 |
| = | 38319 125 | × | 50 10239 |
| = | 12773 5 | × | 2 3413 |
We obtained :
| X | = | 25546 17065 |
Convert the result to decimal form :
| X | = | 1.496982 |
