The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$10 x = 5 x + 20$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 20$$
Divide both parts of the equation by 5
We get the answer: x = 4
10*x-20 = 5*x
Move free summands (without x)
from left part to right part, we given:
$$10 x = 5 x + 20$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 20$$
Divide both parts of the equation by 5
x = 20 / (5)
We get the answer: x = 4
