Work: Find the solution of equation (2300+x)/3.6 = 69.44 .
Question type: Equation
Solution:Original question:
| ( | 2300 | + | x | ) | ÷ | 18 5 | = | 1736 25 |
| Left side of the equation = | 2300 | × | 5 18 | + | x | × | 5 18 |
| = | 5750 9 | + | x | × | 5 18 |
5750 9 | + | 5 18 | x | = | 1736 25 |
Transposition :
5 18 | x | = | 1736 25 | − | 5750 9 |
Combine the items on the right of the equation:
5 18 | x | = | - | 128126 225 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 128126 225 | ÷ | 5 18 |
| = | - | 128126 225 | × | 18 5 |
| = | - | 128126 25 | × | 2 5 |
We obtained :
| x | = | - | 256252 125 |
Convert the result to decimal form :
| x | = | - 2050.016 |
