Work: Find the solution of equation 31.3+x-x*0.015 = 50 .
Question type: Equation
Solution:Original question:
313 10 | + | x | − | x | × | 3 200 | = | 50 |
| Left side of the equation = | 313 10 | + | 197 200 | x |
313 10 | + | 197 200 | x | = | 50 |
Transposition :
197 200 | x | = | 50 | − | 313 10 |
Combine the items on the right of the equation:
197 200 | x | = | 187 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 187 10 | ÷ | 197 200 |
| = | 187 10 | × | 200 197 |
| = | 187 | × | 20 197 |
We obtained :
| x | = | 3740 197 |
Convert the result to decimal form :
| x | = | 18.984772 |
