Work: Find the solution of equation 18.2591(x-20) = 291.47 .
Question type: Equation
Solution:Original question:
182591 10000 | ( | x | − | 20 | ) | = | 29147 100 |
| Left side of the equation = | 182591 10000 | x | − | 182591 10000 | × | 20 |
| = | 182591 10000 | x | − | 182591 500 |
182591 10000 | x | − | 182591 500 | = | 29147 100 |
Transposition :
182591 10000 | x | = | 29147 100 | + | 182591 500 |
Combine the items on the right of the equation:
182591 10000 | x | = | 164163 250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 164163 250 | ÷ | 182591 10000 |
| = | 164163 250 | × | 10000 182591 |
| = | 164163 | × | 40 182591 |
We obtained :
| x | = | 6566520 182591 |
Convert the result to decimal form :
| x | = | 35.962999 |
