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:
$$- 10 x = 5 y + 10$$
Divide both parts of the equation by -10
We get the answer: x = -1 - y/2
-10*x-5*y = 10
Looking for similar summands in the left part:
-10*x - 5*y = 10
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 5 y + 10$$
Divide both parts of the equation by -10
x = 10 + 5*y / (-10)
We get the answer: x = -1 - y/2
