[ 1/1 Equation]
Work: Find the solution of equation (121.7-x)/x = -0.249 .
Question type: Equation
Solution:Original question:
| ( | 1217 10 | − | x | ) | ÷ | x | = | - | 249 1000 |
| Multiply both sides of the equation by: | x |
| ( | 1217 10 | − | x | ) | = | - | 249 1000 | x |
1217 10 | − | x | = | - | 249 1000 | x |
Transposition :
| - | x | + | 249 1000 | x | = | - | 1217 10 |
Combine the items on the left of the equation:
| - | 751 1000 | x | = | - | 1217 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1217 10 | = | 751 1000 | 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 :
751 1000 | x | = | 1217 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1217 10 | ÷ | 751 1000 |
| = | 1217 10 | × | 1000 751 |
| = | 1217 | × | 100 751 |
We obtained :
| x | = | 121700 751 |
Convert the result to decimal form :
| x | = | 162.050599 |
