Work: Find the solution of equation 0.13*x+(x*1.05+200)+0.15*x+(0.13*x*0.1655) = 7566.61 .
Question type: Equation
Solution:Original question:
13 100 | x | + | ( | x | × | 21 20 | + | 200 | ) | + | 3 20 | x | + | ( | 13 100 | x | × | 331 2000 | ) | = | 756661 100 |
| Left side of the equation = | 7 25 | x | + | ( | x | × | 21 20 | + | 200 | ) | + | ( | 13 100 | x | × | 331 2000 | ) |
7 25 | x | + | ( | x | × | 21 20 | + | 200 | ) | + | ( | 13 100 | x | × | 331 2000 | ) | = | 756661 100 |
| Left side of the equation = | 7 25 | x | + | x | × | 21 20 | + | 200 | + | ( | 13 100 | x | × | 331 2000 | ) |
| = | 133 100 | x | + | 200 | + | ( | 13 100 | x | × | 331 2000 | ) |
| = | 133 100 | x | + | 200 | + | 13 100 | x | × | 331 2000 |
| = | 133 100 | x | + | 200 | + | 4303 200000 | x |
| = | 270303 200000 | x | + | 200 |
270303 200000 | x | + | 200 | = | 756661 100 |
Transposition :
270303 200000 | x | = | 756661 100 | − | 200 |
Combine the items on the right of the equation:
270303 200000 | x | = | 736661 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 736661 100 | ÷ | 270303 200000 |
| = | 736661 100 | × | 200000 270303 |
| = | 736661 | × | 2000 270303 |
We obtained :
| x | = | 1473322000 270303 |
Convert the result to decimal form :
| x | = | 5450.631329 |
