Work: Find the solution of equation （x-103.071）*20-0.63-0.63 = 2 .
Question type: Equation
Solution:Original question:
| ( | x | − | 103071 1000 | ) | × | 20 | − | 63 100 | − | 63 100 | = | 2 |
| Left side of the equation = | ( | x | − | 103071 1000 | ) | × | 20 | − | 63 50 |
| ( | x | − | 103071 1000 | ) | × | 20 | − | 63 50 | = | 2 |
| Left side of the equation = | x | × | 20 | − | 103071 1000 | × | 20 | − | 63 50 |
| = | x | × | 20 | − | 103071 50 | − | 63 50 |
| = | 20 | x | − | 51567 25 |
| 20 | x | − | 51567 25 | = | 2 |
Transposition :
| 20 | x | = | 2 | + | 51567 25 |
Combine the items on the right of the equation:
| 20 | x | = | 51617 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 51617 25 | ÷ | 20 |
| = | 51617 25 | × | 1 20 |
We obtained :
| x | = | 51617 500 |
Convert the result to decimal form :
| x | = | 103.234 |
