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:
$$- 4 x = 3 y + 13$$
Divide both parts of the equation by -4
We get the answer: x = -13/4 - 3*y/4
-4*x-3*y = 13
Looking for similar summands in the left part:
-4*x - 3*y = 13
Move the summands with the other variables
from left part to right part, we given:
$$- 4 x = 3 y + 13$$
Divide both parts of the equation by -4
x = 13 + 3*y / (-4)
We get the answer: x = -13/4 - 3*y/4
