Work: Find the solution of equation x/（750+x） = 0.5556 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 750 | + | x | ) | = | 1389 2500 |
| Multiply both sides of the equation by: | ( | 750 | + | x | ) |
| x | = | 1389 2500 | ( | 750 | + | x | ) |
| x | = | 1389 2500 | × | 750 | + | 1389 2500 | x |
| x | = | 4167 10 | + | 1389 2500 | x |
Transposition :
| x | − | 1389 2500 | x | = | 4167 10 |
Combine the items on the left of the equation:
1111 2500 | x | = | 4167 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4167 10 | ÷ | 1111 2500 |
| = | 4167 10 | × | 2500 1111 |
| = | 4167 | × | 250 1111 |
We obtained :
| x | = | 1041750 1111 |
Convert the result to decimal form :
| x | = | 937.668767 |
