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:
$$- 8 x = 15 - 12 y$$
Divide both parts of the equation by -8
We get the answer: x = -15/8 + 3*y/2
-8*x+12*y = 15
Looking for similar summands in the left part:
-8*x + 12*y = 15
Move the summands with the other variables
from left part to right part, we given:
$$- 8 x = 15 - 12 y$$
Divide both parts of the equation by -8
x = 15 - 12*y / (-8)
We get the answer: x = -15/8 + 3*y/2
