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