Work: Find the solution of equation 138.64 = 19.8x+(5-x）29.2 .
Question type: Equation
Solution:Original question:
3466 25 | = | 99 5 | x | + | ( | 5 | − | x | ) | × | 146 5 |
| Right side of the equation = | 99 5 | x | + | 5 | × | 146 5 | − | x | × | 146 5 |
| = | 99 5 | x | + | 146 | − | x | × | 146 5 |
| = | - | 47 5 | x | + | 146 |
3466 25 | = | - | 47 5 | x | + | 146 |
Transposition :
47 5 | x | = | 146 | − | 3466 25 |
Combine the items on the right of the equation:
47 5 | x | = | 184 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 184 25 | ÷ | 47 5 |
| = | 184 25 | × | 5 47 |
| = | 184 5 | × | 1 47 |
We obtained :
| x | = | 184 235 |
Convert the result to decimal form :
| x | = | 0.782979 |
