[ 1/1 Equation]
Work: Find the solution of equation (x+200)/(x+1719) = 0.19 .
Question type: Equation
Solution:Original question:
| ( | x | + | 200 | ) | ÷ | ( | x | + | 1719 | ) | = | 19 100 |
| Multiply both sides of the equation by: | ( | x | + | 1719 | ) |
| ( | x | + | 200 | ) | = | 19 100 | ( | x | + | 1719 | ) |
| x | + | 200 | = | 19 100 | ( | x | + | 1719 | ) |
| x | + | 200 | = | 19 100 | x | + | 19 100 | × | 1719 |
| x | + | 200 | = | 19 100 | x | + | 32661 100 |
Transposition :
| x | − | 19 100 | x | = | 32661 100 | − | 200 |
Combine the items on the left of the equation:
81 100 | x | = | 32661 100 | − | 200 |
Combine the items on the right of the equation:
81 100 | x | = | 12661 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12661 100 | ÷ | 81 100 |
| = | 12661 100 | × | 100 81 |
| = | 12661 | × | 1 81 |
We obtained :
| x | = | 12661 81 |
Convert the result to decimal form :
| x | = | 156.308642 |
