Work: Find the solution of equation (0.075-x)/0.074 = 9.8/39.8 .
Question type: Equation
Solution:Original question:
| ( | 3 40 | − | x | ) | ÷ | 37 500 | = | 49 5 | ÷ | 199 5 |
| Left side of the equation = | 3 40 | × | 500 37 | − | x | × | 500 37 |
| = | 75 74 | − | x | × | 500 37 |
75 74 | − | 500 37 | x | = | 49 5 | ÷ | 199 5 |
| Right side of the equation = | 49 199 |
75 74 | − | 500 37 | x | = | 49 199 |
Transposition :
| - | 500 37 | x | = | 49 199 | − | 75 74 |
Combine the items on the right of the equation:
| - | 500 37 | x | = | - | 11299 14726 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
11299 14726 | = | 500 37 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
500 37 | x | = | 11299 14726 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11299 14726 | ÷ | 500 37 |
| = | 11299 14726 | × | 37 500 |
| = | 11299 398 | × | 1 500 |
We obtained :
| x | = | 11299 199000 |
Convert the result to decimal form :
| x | = | 0.056779 |
