The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$5 x = x + 19$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 19$$
Divide both parts of the equation by 4
We get the answer: x = 19/4
5*x-15 = 4+x
Move free summands (without x)
from left part to right part, we given:
$$5 x = x + 19$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 19$$
Divide both parts of the equation by 4
x = 19 / (4)
We get the answer: x = 19/4
