[ 1/1 Equation]
Work: Find the solution of equation （2x+81.4）*1.08-2x-100.99 = 0 .
Question type: Equation
Solution:Original question:
| ( | 2 | x | + | 407 5 | ) | × | 27 25 | − | 2 | x | − | 10099 100 | = | 0 |
| Left side of the equation = | 2 | x | × | 27 25 | + | 407 5 | × | 27 25 | − | 2 | x | − | 10099 100 |
| = | 54 25 | x | + | 10989 125 | − | 2 | x | − | 10099 100 |
| = | 4 25 | x | − | 6539 500 |
4 25 | x | − | 6539 500 | = | 0 |
Transposition :
4 25 | x | = | 0 | + | 6539 500 |
Combine the items on the right of the equation:
4 25 | x | = | 6539 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6539 500 | ÷ | 4 25 |
| = | 6539 500 | × | 25 4 |
| = | 6539 20 | × | 1 4 |
We obtained :
| x | = | 6539 80 |
Convert the result to decimal form :
| x | = | 81.7375 |
