Work: Find the solution of equation 4.32*（25-x）+216.2 = （6.48*x+192+50）/1.5 .
Question type: Equation
Solution:Original question:
108 25 | ( | 25 | − | x | ) | + | 1081 5 | = | ( | 162 25 | x | + | 192 | + | 50 | ) | ÷ | 3 2 |
| Left side of the equation = | 108 25 | × | 25 | − | 108 25 | x | + | 1081 5 |
| = | 108 | − | 108 25 | x | + | 1081 5 |
| = | 1621 5 | − | 108 25 | x |
1621 5 | − | 108 25 | x | = | ( | 162 25 | x | + | 192 | + | 50 | ) | ÷ | 3 2 |
| Right side of the equation = | 162 25 | x | × | 2 3 | + | 192 | × | 2 3 | + | 50 | × | 2 3 |
| = | 108 25 | x | + | 128 | + | 100 3 |
| = | 108 25 | x | + | 484 3 |
1621 5 | − | 108 25 | x | = | 108 25 | x | + | 484 3 |
Transposition :
| - | 108 25 | x | − | 108 25 | x | = | 484 3 | − | 1621 5 |
Combine the items on the left of the equation:
| - | 216 25 | x | = | 484 3 | − | 1621 5 |
Combine the items on the right of the equation:
| - | 216 25 | x | = | - | 2443 15 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
2443 15 | = | 216 25 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
216 25 | x | = | 2443 15 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2443 15 | ÷ | 216 25 |
| = | 2443 15 | × | 25 216 |
| = | 2443 3 | × | 5 216 |
We obtained :
| x | = | 12215 648 |
Convert the result to decimal form :
| x | = | 18.850309 |
