Work: Find the solution of equation (0.09*2.128+2*x)/(2.128+x)-0.1 = 0 .
Question type: Equation
Solution:Original question:
| ( | 9 100 | × | 266 125 | + | 2 | x | ) | ÷ | ( | 266 125 | + | x | ) | − | 1 10 | = | 0 |
| Multiply both sides of the equation by: | ( | 266 125 | + | x | ) |
| ( | 9 100 | × | 266 125 | + | 2 | x | ) | − | 1 10 | ( | 266 125 | + | x | ) | = | 0 |
9 100 | × | 266 125 | + | 2 | x | − | 1 10 | ( | 266 125 | + | x | ) | = | 0 |
1197 6250 | + | 2 | x | − | 1 10 | ( | 266 125 | + | x | ) | = | 0 |
1197 6250 | + | 2 | x | − | 1 10 | × | 266 125 | − | 1 10 | x | = | 0 |
1197 6250 | + | 2 | x | − | 133 625 | − | 1 10 | x | = | 0 |
| - | 133 6250 | + | 19 10 | x | = | 0 |
Transposition :
19 10 | x | = | 0 | + | 133 6250 |
Combine the items on the right of the equation:
19 10 | x | = | 133 6250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 133 6250 | ÷ | 19 10 |
| = | 133 6250 | × | 10 19 |
| = | 7 625 | × | 1 |
We obtained :
| x | = | 7 625 |
Convert the result to decimal form :
| x | = | 0.0112 |
