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:
$$- 16 x = 12 - 12 y$$
Divide both parts of the equation by -16
We get the answer: x = -3/4 + 3*y/4
-16*x+12*y = 12
Looking for similar summands in the left part:
-16*x + 12*y = 12
Move the summands with the other variables
from left part to right part, we given:
$$- 16 x = 12 - 12 y$$
Divide both parts of the equation by -16
x = 12 - 12*y / (-16)
We get the answer: x = -3/4 + 3*y/4
