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
