☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x/(100+x) = 0.1042 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 100 | + | x | ) | = | 521 5000 |
| Multiply both sides of the equation by: | ( | 100 | + | x | ) |
| x | = | 521 5000 | ( | 100 | + | x | ) |
| x | = | 521 5000 | × | 100 | + | 521 5000 | x |
| x | = | 521 50 | + | 521 5000 | x |
Transposition :
| x | − | 521 5000 | x | = | 521 50 |
Combine the items on the left of the equation:
4479 5000 | x | = | 521 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 521 50 | ÷ | 4479 5000 |
| = | 521 50 | × | 5000 4479 |
| = | 521 | × | 100 4479 |
We obtained :
| x | = | 52100 4479 |
Convert the result to decimal form :
| x | = | 11.632061 |
