[ 1/1 Equation]
Work: Find the solution of equation (x+400*0.2%+x*1.5%+x*10%)+(x+x*10%) = 586.7 .
Question type: Equation
Solution:Original question:
| ( | x | + | 400 | × | 1 500 | + | x | × | 3 200 | + | x | × | 10 100 | ) | + | ( | x | + | x | × | 10 100 | ) | = | 5867 10 |
| Left side of the equation = | x | + | 400 | × | 1 500 | + | x | × | 3 200 | + | x | × | 10 100 | + | ( | x | + | x | × | 10 100 | ) |
| = | x | + | 4 5 | + | x | × | 3 200 | + | x | × | 10 100 | + | ( | x | + | x | × | 10 100 | ) |
| = | 223 200 | x | + | 4 5 | + | ( | x | + | x | × | 10 100 | ) |
| = | 223 200 | x | + | 4 5 | + | x | + | x | × | 10 100 |
| = | 443 200 | x | + | 4 5 |
443 200 | x | + | 4 5 | = | 5867 10 |
Transposition :
443 200 | x | = | 5867 10 | − | 4 5 |
Combine the items on the right of the equation:
443 200 | x | = | 5859 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 5859 10 | ÷ | 443 200 |
| = | 5859 10 | × | 200 443 |
| = | 5859 | × | 20 443 |
We obtained :
| x | = | 117180 443 |
Convert the result to decimal form :
| x | = | 264.514673 |
