[ 1/1 Equation]
Work: Find the solution of equation 0.892 = 2*(0.981*x)/(0.98+x) .
Question type: Equation
Solution:Original question:
223 250 | = | 2 | ( | 981 1000 | x | ) | ÷ | ( | 49 50 | + | x | ) |
| Multiply both sides of the equation by: | ( | 49 50 | + | x | ) |
223 250 | ( | 49 50 | + | x | ) | = | 2 | ( | 981 1000 | x | ) |
223 250 | × | 49 50 | + | 223 250 | x | = | 2 | ( | 981 1000 | x | ) |
223 250 | × | 49 50 | + | 223 250 | x | = | 2 | × | 981 1000 | x |
10927 12500 | + | 223 250 | x | = | 981 500 | x |
Transposition :
223 250 | x | − | 981 500 | x | = | - | 10927 12500 |
Combine the items on the left of the equation:
| - | 107 100 | x | = | - | 10927 12500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
10927 12500 | = | 107 100 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
107 100 | x | = | 10927 12500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 10927 12500 | ÷ | 107 100 |
| = | 10927 12500 | × | 100 107 |
| = | 10927 125 | × | 1 107 |
We obtained :
| x | = | 10927 13375 |
Convert the result to decimal form :
| x | = | 0.816972 |
