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