Work: Find the solution of equation 848*x = 0.8*(848*x+(512.7-x)*459) .
Question type: Equation
Solution:Original question:
| 848 | x | = | 4 5 | ( | 848 | x | + | ( | 5127 10 | − | x | ) | × | 459 | ) |
| Right side of the equation = | 4 5 | × | 848 | x | + | 4 5 | ( | 5127 10 | − | x | ) | × | 459 |
| = | 3392 5 | x | + | 1836 5 | ( | 5127 10 | − | x | ) |
| = | 3392 5 | x | + | 1836 5 | × | 5127 10 | − | 1836 5 | x |
| = | 3392 5 | x | + | 4706586 25 | − | 1836 5 | x |
| = | 1556 5 | x | + | 4706586 25 |
| 848 | x | = | 1556 5 | x | + | 4706586 25 |
Transposition :
| 848 | x | − | 1556 5 | x | = | 4706586 25 |
Combine the items on the left of the equation:
2684 5 | x | = | 4706586 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4706586 25 | ÷ | 2684 5 |
| = | 4706586 25 | × | 5 2684 |
| = | 2353293 5 | × | 1 1342 |
We obtained :
| x | = | 2353293 6710 |
Convert the result to decimal form :
| x | = | 350.714307 |
