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:
-5*y + 10*x = 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
