Work: Find the solution of equation （x+15000）÷（x+19926.27） = 0.8 .
Question type: Equation
Solution:Original question:
| ( | x | + | 15000 | ) | ÷ | ( | x | + | 1992627 100 | ) | = | 4 5 |
| Multiply both sides of the equation by: | ( | x | + | 1992627 100 | ) |
| ( | x | + | 15000 | ) | = | 4 5 | ( | x | + | 1992627 100 | ) |
| x | + | 15000 | = | 4 5 | ( | x | + | 1992627 100 | ) |
| x | + | 15000 | = | 4 5 | x | + | 4 5 | × | 1992627 100 |
| x | + | 15000 | = | 4 5 | x | + | 1992627 125 |
Transposition :
| x | − | 4 5 | x | = | 1992627 125 | − | 15000 |
Combine the items on the left of the equation:
1 5 | x | = | 1992627 125 | − | 15000 |
Combine the items on the right of the equation:
1 5 | x | = | 117627 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 117627 125 | ÷ | 1 5 |
| = | 117627 125 | × | 5 |
| = | 117627 25 | × | 1 |
We obtained :
| x | = | 117627 25 |
Convert the result to decimal form :
| x | = | 4705.08 |
