Work: Find the solution of equation 1108*4.89+5x-7*5+4/1100+x-8 = 4.9 .
Question type: Equation
Solution:Original question:
| 1108 | × | 489 100 | + | 5 | x | − | 7 | × | 5 | + | 4 | ÷ | 1100 | + | x | − | 8 | = | 49 10 |
| Left side of the equation = | 135453 25 | + | 5 | x | − | 35 | + | 1 275 | + | x | − | 8 |
| = | 1478159 275 | + | 6 | x |
1478159 275 | + | 6 | x | = | 49 10 |
Transposition :
| 6 | x | = | 49 10 | − | 1478159 275 |
Combine the items on the right of the equation:
| 6 | x | = | - | 2953623 550 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 2953623 550 | ÷ | 6 |
| = | - | 2953623 550 | × | 1 6 |
| = | - | 984541 550 | × | 1 2 |
We obtained :
| x | = | - | 984541 1100 |
Convert the result to decimal form :
| x | = | - 895.037273 |
