Work: Find the solution of equation 18/(11.46+x)/2 = 1.74 .
Question type: Equation
Solution:Original question:
| 18 | ÷ | ( | 573 50 | + | x | ) | ÷ | 2 | = | 87 50 |
| Multiply both sides of the equation by: | ( | 573 50 | + | x | ) |
| 18 | ÷ | 2 | = | 87 50 | ( | 573 50 | + | x | ) |
| 18 | ÷ | 2 | = | 87 50 | × | 573 50 | + | 87 50 | x |
| 9 | = | 49851 2500 | + | 87 50 | x |
Transposition :
| - | 87 50 | x | = | 49851 2500 | − | 9 |
Combine the items on the right of the equation:
| - | 87 50 | x | = | 27351 2500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 27351 2500 | = | 87 50 | 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 :
87 50 | x | = | - | 27351 2500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 27351 2500 | ÷ | 87 50 |
| = | - | 27351 2500 | × | 50 87 |
| = | - | 9117 50 | × | 1 29 |
We obtained :
| x | = | - | 9117 1450 |
Convert the result to decimal form :
| x | = | - 6.287586 |
