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:
$$- 14 x = 8 y + 20$$
Divide both parts of the equation by -14
We get the answer: x = -10/7 - 4*y/7
-14*x-8*y = 20
Looking for similar summands in the left part:
-14*x - 8*y = 20
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = 8 y + 20$$
Divide both parts of the equation by -14
x = 20 + 8*y / (-14)
We get the answer: x = -10/7 - 4*y/7
