Work: Find the solution of equation 13.6-1.3x = 12.934 .
Question type: Equation
Solution:Original question:
68 5 | − | 13 10 | x | = | 6467 500 |
Transposition :
| - | 13 10 | x | = | 6467 500 | − | 68 5 |
Combine the items on the right of the equation:
| - | 13 10 | x | = | - | 333 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
333 500 | = | 13 10 | 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 :
13 10 | x | = | 333 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 333 500 | ÷ | 13 10 |
| = | 333 500 | × | 10 13 |
| = | 333 50 | × | 1 13 |
We obtained :
| x | = | 333 650 |
Convert the result to decimal form :
| x | = | 0.512308 |
