Work: Find the solution of equation （x-5000）*10%-2520 = 77.94 .
Question type: Equation
Solution:Original question:
| ( | x | − | 5000 | ) | × | 10 100 | − | 2520 | = | 3897 50 |
| Left side of the equation = | x | × | 10 100 | − | 5000 | × | 10 100 | − | 2520 |
| = | x | × | 10 100 | − | 500 | − | 2520 |
| = | 10 100 | x | − | 3020 |
10 100 | x | − | 3020 | = | 3897 50 |
Transposition :
10 100 | x | = | 3897 50 | + | 3020 |
Combine the items on the right of the equation:
10 100 | x | = | 154897 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 154897 50 | ÷ | 10 100 |
| = | 154897 50 | × | 100 10 |
| = | 154897 | × | 2 10 |
We obtained :
| x | = | 309794 10 |
By reducing fraction, we can get:
| x | = | 154897 5 |
Convert the result to decimal form :
| x | = | 30979.4 |
