Work: Find the solution of equation 2.6x-6.5+3.5 = 10 .
Question type: Equation
Solution:Original question:
13 5 | x | − | 13 2 | + | 7 2 | = | 10 |
| Left side of the equation = | 13 5 | x | − | 3 |
13 5 | x | − | 3 | = | 10 |
Transposition :
13 5 | x | = | 10 | + | 3 |
Combine the items on the right of the equation:
13 5 | x | = | 13 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 13 | ÷ | 13 5 |
| = | 13 | × | 5 13 |
| = | 1 | × | 5 |
We obtained :
| x | = | 5 |
