Work: Find the solution of equation (2783.346-x)/x*100% = 1.29% .
Question type: Equation
Solution:Original question:
| ( | 1391673 500 | − | x | ) | ÷ | x | × | 100 100 | = | 129 10000 |
| Multiply both sides of the equation by: | x |
| ( | 1391673 500 | − | x | ) | × | 100 100 | = | 129 10000 | x |
1391673 500 | × | 100 100 | − | x | × | 100 100 | = | 129 10000 | x |
1391673 500 | − | x | × | 100 100 | = | 129 10000 | x |
Transposition :
| - | 100 100 | x | − | 129 10000 | x | = | - | 1391673 500 |
Combine the items on the left of the equation:
| - | 10129 10000 | x | = | - | 1391673 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1391673 500 | = | 10129 10000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
10129 10000 | x | = | 1391673 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1391673 500 | ÷ | 10129 10000 |
| = | 1391673 500 | × | 10000 10129 |
| = | 1391673 | × | 20 10129 |
We obtained :
| x | = | 27833460 10129 |
Convert the result to decimal form :
| x | = | 2747.898114 |
