The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 13 y + 13$$
Divide both parts of the equation by 4
We get the answer: x = 13/4 + 13*y/4
4*x-13*y = 13
Looking for similar summands in the left part:
-13*y + 4*x = 13
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 13 y + 13$$
Divide both parts of the equation by 4
x = 13 + 13*y / (4)
We get the answer: x = 13/4 + 13*y/4
