Work: Find the solution of equation (2.79+2x)/(2.79+x)-1 = 0.33% .
Question type: Equation
Solution:Original question:
| ( | 279 100 | + | 2 | x | ) | ÷ | ( | 279 100 | + | x | ) | − | 1 | = | 33 10000 |
| Multiply both sides of the equation by: | ( | 279 100 | + | x | ) |
| ( | 279 100 | + | 2 | x | ) | − | 1 | ( | 279 100 | + | x | ) | = | 33 10000 | ( | 279 100 | + | x | ) |
279 100 | + | 2 | x | − | 1 | ( | 279 100 | + | x | ) | = | 33 10000 | ( | 279 100 | + | x | ) |
279 100 | + | 2 | x | − | 1 | ( | 279 100 | + | x | ) | = | 33 10000 | × | 279 100 | + | 33 10000 | x |
279 100 | + | 2 | x | − | 1 | ( | 279 100 | + | x | ) | = | 9207 1000000 | + | 33 10000 | x |
279 100 | + | 2 | x | − | 1 | × | 279 100 | − | 1 | x | = | 9207 1000000 | + | 33 10000 | x |
279 100 | + | 2 | x | − | 279 100 | − | 1 | x | = | 9207 1000000 | + | 33 10000 | x |
| 0 | + | 1 | x | = | 9207 1000000 | + | 33 10000 | x |
Transposition :
| 1 | x | − | 33 10000 | x | = | 9207 1000000 |
Combine the items on the left of the equation:
9967 10000 | x | = | 9207 1000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 9207 1000000 | ÷ | 9967 10000 |
| = | 9207 1000000 | × | 10000 9967 |
| = | 9207 100 | × | 1 9967 |
We obtained :
| x | = | 9207 996700 |
Convert the result to decimal form :
| x | = | 0.009237 |
