[ 1/1 Equation]
Work: Find the solution of equation 74*1.82-x = x*9.95-74 .
Question type: Equation
Solution:Original question:
| 74 | × | 91 50 | − | x | = | x | × | 199 20 | − | 74 |
| Left side of the equation = | 3367 25 | − | x |
3367 25 | − | x | = | x | × | 199 20 | − | 74 |
Transposition :
| - | x | − | 199 20 | x | = | - | 74 | − | 3367 25 |
Combine the items on the left of the equation:
| - | 219 20 | x | = | - | 74 | − | 3367 25 |
Combine the items on the right of the equation:
| - | 219 20 | x | = | - | 5217 25 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5217 25 | = | 219 20 | 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 :
219 20 | x | = | 5217 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 5217 25 | ÷ | 219 20 |
| = | 5217 25 | × | 20 219 |
| = | 1739 5 | × | 4 73 |
We obtained :
| x | = | 6956 365 |
Convert the result to decimal form :
| x | = | 19.057534 |
