Work: Find the solution of equation 245/149 = 28-x/18.4-x .
Question type: Equation
Solution:Original question:
| 245 | ÷ | 149 | = | 28 | − | x | ÷ | 92 5 | − | x |
| Left side of the equation = | 245 149 |
245 149 | = | 28 | − | x | ÷ | 92 5 | − | x |
| Right side of the equation = | 28 | − | 97 92 | x |
245 149 | = | 28 | − | 97 92 | x |
Transposition :
97 92 | x | = | 28 | − | 245 149 |
Combine the items on the right of the equation:
97 92 | x | = | 3927 149 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3927 149 | ÷ | 97 92 |
| = | 3927 149 | × | 92 97 |
We obtained :
| x | = | 361284 14453 |
Convert the result to decimal form :
| x | = | 24.997163 |
