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:
$$8 x = 4 y + 10$$
Divide both parts of the equation by 8
We get the answer: x = 5/4 + y/2
8*x-4*y = 10
Looking for similar summands in the left part:
-4*y + 8*x = 10
Move the summands with the other variables
from left part to right part, we given:
$$8 x = 4 y + 10$$
Divide both parts of the equation by 8
x = 10 + 4*y / (8)
We get the answer: x = 5/4 + y/2
