Work: Find the solution of equation (1.48x+5)/1.85-5-(1.48x+5)/18 = 0 .
Question type: Equation
Solution:Original question:
| ( | 37 25 | x | + | 5 | ) | ÷ | 37 20 | − | 5 | − | ( | 37 25 | x | + | 5 | ) | ÷ | 18 | = | 0 |
| Left side of the equation = | 37 25 | x | × | 20 37 | + | 5 | × | 20 37 | − | 5 | − | ( | 37 25 | x | + | 5 | ) | × | 1 18 |
| = | 4 5 | x | + | 100 37 | − | 5 | − | ( | 37 25 | x | + | 5 | ) | × | 1 18 |
| = | 4 5 | x | − | 85 37 | − | ( | 37 25 | x | + | 5 | ) | × | 1 18 |
| = | 4 5 | x | − | 85 37 | − | 37 25 | x | × | 1 18 | − | 5 | × | 1 18 |
| = | 4 5 | x | − | 85 37 | − | 37 450 | x | − | 5 18 |
| = | 323 450 | x | − | 1715 666 |
323 450 | x | − | 1715 666 | = | 0 |
Transposition :
323 450 | x | = | 0 | + | 1715 666 |
Combine the items on the right of the equation:
323 450 | x | = | 1715 666 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1715 666 | ÷ | 323 450 |
| = | 1715 666 | × | 450 323 |
| = | 1715 37 | × | 25 323 |
We obtained :
| x | = | 42875 11951 |
Convert the result to decimal form :
| x | = | 3.587566 |
