☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x/(100+x) = 0.247 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | 100 | + | x | ) | = | 247 1000 |
| Multiply both sides of the equation by: | ( | 100 | + | x | ) |
| x | = | 247 1000 | ( | 100 | + | x | ) |
| x | = | 247 1000 | × | 100 | + | 247 1000 | x |
| x | = | 247 10 | + | 247 1000 | x |
Transposition :
| x | − | 247 1000 | x | = | 247 10 |
Combine the items on the left of the equation:
753 1000 | x | = | 247 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 247 10 | ÷ | 753 1000 |
| = | 247 10 | × | 1000 753 |
| = | 247 | × | 100 753 |
We obtained :
| x | = | 24700 753 |
Convert the result to decimal form :
| x | = | 32.802125 |
