Work: Find the solution of equation 100x-x = 394.02 .
Question type: Equation
Solution:Original question:
| 100 | x | − | x | = | 19701 50 |
| Left side of the equation = | 99 | x |
| 99 | x | = | 19701 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 19701 50 | ÷ | 99 |
| = | 19701 50 | × | 1 99 |
| = | 199 50 | × | 1 |
We obtained :
| x | = | 199 50 |
Convert the result to decimal form :
| x | = | 3.98 |
