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:
$$5 x = 14 - 2 y$$
Divide both parts of the equation by 5
We get the answer: x = 14/5 - 2*y/5
5*x+2*y = 14
Looking for similar summands in the left part:
2*y + 5*x = 14
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 14 - 2 y$$
Divide both parts of the equation by 5
x = 14 - 2*y / (5)
We get the answer: x = 14/5 - 2*y/5
