Work: Find the solution of equation 1150*x = 0.75*(1150*x+(689.9-x)*475) .
Question type: Equation
Solution:Original question:
| 1150 | x | = | 3 4 | ( | 1150 | x | + | ( | 6899 10 | − | x | ) | × | 475 | ) |
| Right side of the equation = | 3 4 | × | 1150 | x | + | 3 4 | ( | 6899 10 | − | x | ) | × | 475 |
| = | 1725 2 | x | + | 1425 4 | ( | 6899 10 | − | x | ) |
| = | 1725 2 | x | + | 1425 4 | × | 6899 10 | − | 1425 4 | x |
| = | 1725 2 | x | + | 1966215 8 | − | 1425 4 | x |
| = | 2025 4 | x | + | 1966215 8 |
| 1150 | x | = | 2025 4 | x | + | 1966215 8 |
Transposition :
| 1150 | x | − | 2025 4 | x | = | 1966215 8 |
Combine the items on the left of the equation:
2575 4 | x | = | 1966215 8 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1966215 8 | ÷ | 2575 4 |
| = | 1966215 8 | × | 4 2575 |
| = | 393243 2 | × | 1 515 |
We obtained :
| x | = | 393243 1030 |
Convert the result to decimal form :
| x | = | 381.78932 |
