[ 1/1 Equation]
Work: Find the solution of equation x/(x+10+75) = 9%/100% .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | x | + | 10 | + | 75 | ) | = | 9 100 | ÷ | 100 100 |
| Multiply both sides of the equation by: | ( | x | + | 10 | + | 75 | ) |
| x | = | 9 100 | ÷ | 100 100 | × | ( | x | + | 10 | + | 75 | ) |
| x | = | 9 100 | ÷ | 100 100 | × | x | + | 9 100 | ÷ | 100 100 | × | 10 | + | 9 100 | ÷ | 100 100 | × | 75 |
| x | = | 9 100 | x | + | 9 10 | + | 27 4 |
| x | = | 9 100 | x | + | 153 20 |
Transposition :
| x | − | 9 100 | x | = | 153 20 |
Combine the items on the left of the equation:
91 100 | x | = | 153 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 153 20 | ÷ | 91 100 |
| = | 153 20 | × | 100 91 |
| = | 153 | × | 5 91 |
We obtained :
| x | = | 765 91 |
Convert the result to decimal form :
| x | = | 8.406593 |
