Work: Find the solution of equation 99*x*7.9 = 57 .
Question type: Equation
Solution:Original question:
| 99 | x | × | 79 10 | = | 57 |
| Left side of the equation = | 7821 10 | x |
7821 10 | x | = | 57 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 57 | ÷ | 7821 10 |
| = | 57 | × | 10 7821 |
| = | 19 | × | 10 2607 |
We obtained :
| x | = | 190 2607 |
Convert the result to decimal form :
| x | = | 0.072881 |
