The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$8 x = 39 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$13 x = 39$$
Divide both parts of the equation by 13
We get the answer: x = 3
33+8*x = -5*x+72
Move free summands (without x)
from left part to right part, we given:
$$8 x = 39 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$13 x = 39$$
Divide both parts of the equation by 13
x = 39 / (13)
We get the answer: x = 3
