[ 1/1 Equation]
Work: Find the solution of equation 212.796-4.3(3.2x+6.4) = 6.6x .
Question type: Equation
Solution:Original question:
53199 250 | − | 43 10 | ( | 16 5 | x | + | 32 5 | ) | = | 33 5 | x |
| Left side of the equation = | 53199 250 | − | 43 10 | × | 16 5 | x | − | 43 10 | × | 32 5 |
| = | 53199 250 | − | 344 25 | x | − | 688 25 |
| = | 46319 250 | − | 344 25 | x |
46319 250 | − | 344 25 | x | = | 33 5 | x |
Transposition :
| - | 344 25 | x | − | 33 5 | x | = | - | 46319 250 |
Combine the items on the left of the equation:
| - | 509 25 | x | = | - | 46319 250 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
46319 250 | = | 509 25 | 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 :
509 25 | x | = | 46319 250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 46319 250 | ÷ | 509 25 |
| = | 46319 250 | × | 25 509 |
| = | 46319 10 | × | 1 509 |
We obtained :
| x | = | 46319 5090 |
Convert the result to decimal form :
| x | = | 9.1 |
