Work: Find the solution of equation (1.224+2x)/(1.224+x)-1 = 0.35% .
Question type: Equation
Solution:Original question:
| ( | 153 125 | + | 2 | x | ) | ÷ | ( | 153 125 | + | x | ) | − | 1 | = | 7 2000 |
| Multiply both sides of the equation by: | ( | 153 125 | + | x | ) |
| ( | 153 125 | + | 2 | x | ) | − | 1 | ( | 153 125 | + | x | ) | = | 7 2000 | ( | 153 125 | + | x | ) |
153 125 | + | 2 | x | − | 1 | ( | 153 125 | + | x | ) | = | 7 2000 | ( | 153 125 | + | x | ) |
153 125 | + | 2 | x | − | 1 | ( | 153 125 | + | x | ) | = | 7 2000 | × | 153 125 | + | 7 2000 | x |
153 125 | + | 2 | x | − | 1 | ( | 153 125 | + | x | ) | = | 1071 250000 | + | 7 2000 | x |
153 125 | + | 2 | x | − | 1 | × | 153 125 | − | 1 | x | = | 1071 250000 | + | 7 2000 | x |
153 125 | + | 2 | x | − | 153 125 | − | 1 | x | = | 1071 250000 | + | 7 2000 | x |
| 0 | + | 1 | x | = | 1071 250000 | + | 7 2000 | x |
Transposition :
| 1 | x | − | 7 2000 | x | = | 1071 250000 |
Combine the items on the left of the equation:
1993 2000 | x | = | 1071 250000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1071 250000 | ÷ | 1993 2000 |
| = | 1071 250000 | × | 2000 1993 |
| = | 1071 125 | × | 1 1993 |
We obtained :
| x | = | 1071 249125 |
Convert the result to decimal form :
| x | = | 0.004299 |
