Work: Find the solution of equation 2563+x*5-4.87*2563 = 0 .
Question type: Equation
Solution:Original question:
| 2563 | + | x | × | 5 | − | 487 100 | × | 2563 | = | 0 |
| Left side of the equation = | 2563 | + | x | × | 5 | − | 1248181 100 |
| = | - | 991881 100 | + | 5 | x |
| - | 991881 100 | + | 5 | x | = | 0 |
Transposition :
| 5 | x | = | 0 | + | 991881 100 |
Combine the items on the right of the equation:
| 5 | x | = | 991881 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 991881 100 | ÷ | 5 |
| = | 991881 100 | × | 1 5 |
We obtained :
| x | = | 991881 500 |
Convert the result to decimal form :
| x | = | 1983.762 |
