Work: Find the solution of equation 21.9109(x-20) = 356.544 .
Question type: Equation
Solution:Original question:
219109 10000 | ( | x | − | 20 | ) | = | 44568 125 |
| Left side of the equation = | 219109 10000 | x | − | 219109 10000 | × | 20 |
| = | 219109 10000 | x | − | 219109 500 |
219109 10000 | x | − | 219109 500 | = | 44568 125 |
Transposition :
219109 10000 | x | = | 44568 125 | + | 219109 500 |
Combine the items on the right of the equation:
219109 10000 | x | = | 397381 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 397381 500 | ÷ | 219109 10000 |
| = | 397381 500 | × | 10000 219109 |
| = | 397381 | × | 20 219109 |
We obtained :
| x | = | 7947620 219109 |
Convert the result to decimal form :
| x | = | 36.272449 |
