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:
$$3 x = - 20 y - 4$$
Divide both parts of the equation by 3
We get the answer: x = -4/3 - 20*y/3
3*x+20*y = -4
Looking for similar summands in the left part:
3*x + 20*y = -4
Move the summands with the other variables
from left part to right part, we given:
$$3 x = - 20 y - 4$$
Divide both parts of the equation by 3
x = -4 - 20*y / (3)
We get the answer: x = -4/3 - 20*y/3
