[ 1/1 Equation]
Work: Find the solution of equation 7200 = 3.25*(x/28-x/44.7) .
Question type: Equation
Solution:Original question:
| 7200 | = | 13 4 | ( | x | ÷ | 28 | − | x | ÷ | 447 10 | ) |
| Right side of the equation = | 13 4 | x | ÷ | 28 | − | 13 4 | x | ÷ | 447 10 |
| = | 13 112 | x | − | 65 894 | x |
| = | 2171 50064 | x |
| 7200 | = | 2171 50064 | x |
Transposition :
| - | 2171 50064 | x | = | - | 7200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 7200 | = | 2171 50064 | 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 :
2171 50064 | x | = | 7200 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 7200 | ÷ | 2171 50064 |
| = | 7200 | × | 50064 2171 |
We obtained :
| x | = | 360460800 2171 |
Convert the result to decimal form :
| x | = | 166034.454169 |
