☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x/(100+x) = 0.0348 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 100 | + | x | ) | = | 87 2500 |
| Multiply both sides of the equation by: | ( | 100 | + | x | ) |
| x | = | 87 2500 | ( | 100 | + | x | ) |
| x | = | 87 2500 | × | 100 | + | 87 2500 | x |
| x | = | 87 25 | + | 87 2500 | x |
Transposition :
| x | − | 87 2500 | x | = | 87 25 |
Combine the items on the left of the equation:
2413 2500 | x | = | 87 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 87 25 | ÷ | 2413 2500 |
| = | 87 25 | × | 2500 2413 |
| = | 87 | × | 100 2413 |
We obtained :
| x | = | 8700 2413 |
Convert the result to decimal form :
| x | = | 3.60547 |
