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:
$$- 4 x = - 14 y - 2$$
Divide both parts of the equation by -4
We get the answer: x = 1/2 + 7*y/2
-4*x+14*y = -2
Looking for similar summands in the left part:
-4*x + 14*y = -2
Move the summands with the other variables
from left part to right part, we given:
$$- 4 x = - 14 y - 2$$
Divide both parts of the equation by -4
x = -2 - 14*y / (-4)
We get the answer: x = 1/2 + 7*y/2
