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:
$$6 x = 15 - 20 y$$
Divide both parts of the equation by 6
We get the answer: x = 5/2 - 10*y/3
6*x+20*y = 15
Looking for similar summands in the left part:
6*x + 20*y = 15
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 15 - 20 y$$
Divide both parts of the equation by 6
x = 15 - 20*y / (6)
We get the answer: x = 5/2 - 10*y/3
