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:
$$3 x = 14 y - 2$$
Divide both parts of the equation by 3
We get the answer: x = -2/3 + 14*y/3
3*x-14*y = -2
Looking for similar summands in the left part:
-14*y + 3*x = -2
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 14 y - 2$$
Divide both parts of the equation by 3
x = -2 + 14*y / (3)
We get the answer: x = -2/3 + 14*y/3
