The solution

You have entered [src]
25*x + 6*y = 13
$$25 x + 6 y = 13$$
Detail solution
Given the linear equation:
25*x+6*y = 13

Looking for similar summands in the left part:
6*y + 25*x = 13

Move the summands with the other variables
from left part to right part, we given:
$$25 x = 13 - 6 y$$
Divide both parts of the equation by 25
x = 13 - 6*y / (25)

We get the answer: x = 13/25 - 6*y/25
