Work: Find the solution of equation (0.52*x+11.673*700)/(x+700) = 9.4 .
Question type: Equation
Solution:Original question:
| ( | 13 25 | x | + | 11673 1000 | × | 700 | ) | ÷ | ( | x | + | 700 | ) | = | 47 5 |
| Multiply both sides of the equation by: | ( | x | + | 700 | ) |
| ( | 13 25 | x | + | 11673 1000 | × | 700 | ) | = | 47 5 | ( | x | + | 700 | ) |
13 25 | x | + | 11673 1000 | × | 700 | = | 47 5 | ( | x | + | 700 | ) |
13 25 | x | + | 11673 1000 | × | 700 | = | 47 5 | x | + | 47 5 | × | 700 |
13 25 | x | + | 81711 10 | = | 47 5 | x | + | 6580 |
Transposition :
13 25 | x | − | 47 5 | x | = | 6580 | − | 81711 10 |
Combine the items on the left of the equation:
| - | 222 25 | x | = | 6580 | − | 81711 10 |
Combine the items on the right of the equation:
| - | 222 25 | x | = | - | 15911 10 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
15911 10 | = | 222 25 | 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 :
222 25 | x | = | 15911 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 15911 10 | ÷ | 222 25 |
| = | 15911 10 | × | 25 222 |
| = | 15911 2 | × | 5 222 |
We obtained :
| x | = | 79555 444 |
Convert the result to decimal form :
| x | = | 179.177928 |
