Work: Find the solution of equation 50×8.01+80.6x = 130.6×7.95 .
Question type: Equation
Solution:Original question:
| 50 | × | 801 100 | + | 403 5 | x | = | 653 5 | × | 159 20 |
| Left side of the equation = | 801 2 | + | 403 5 | x |
801 2 | + | 403 5 | x | = | 653 5 | × | 159 20 |
| Right side of the equation = | 103827 100 |
801 2 | + | 403 5 | x | = | 103827 100 |
Transposition :
403 5 | x | = | 103827 100 | − | 801 2 |
Combine the items on the right of the equation:
403 5 | x | = | 63777 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 63777 100 | ÷ | 403 5 |
| = | 63777 100 | × | 5 403 |
| = | 63777 20 | × | 1 403 |
We obtained :
| x | = | 63777 8060 |
Convert the result to decimal form :
| x | = | 7.912779 |
