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:
$$2 x = - 19 y - 7$$
Divide both parts of the equation by 2
We get the answer: x = -7/2 - 19*y/2
2*x+19*y = -7
Looking for similar summands in the left part:
2*x + 19*y = -7
Move the summands with the other variables
from left part to right part, we given:
$$2 x = - 19 y - 7$$
Divide both parts of the equation by 2
x = -7 - 19*y / (2)
We get the answer: x = -7/2 - 19*y/2
