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:
$$2 x = - y - 8$$
Divide both parts of the equation by 2
We get the answer: x = -4 - y/2
2*x+1*y = -8
Looking for similar summands in the left part:
y + 2*x = -8
Move the summands with the other variables
from left part to right part, we given:
$$2 x = - y - 8$$
Divide both parts of the equation by 2
x = -8 - y / (2)
We get the answer: x = -4 - y/2
