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:
$$14 x = 4 y + 20$$
Divide both parts of the equation by 14
We get the answer: x = 10/7 + 2*y/7
14*x-4*y = 20
Looking for similar summands in the left part:
-4*y + 14*x = 20
Move the summands with the other variables
from left part to right part, we given:
$$14 x = 4 y + 20$$
Divide both parts of the equation by 14
x = 20 + 4*y / (14)
We get the answer: x = 10/7 + 2*y/7
