The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$18 x = 6 x + 33$$
Move the summands with the unknown x
from the right part to the left part:
$$12 x = 33$$
Divide both parts of the equation by 12
We get the answer: x = 11/4
18*x-15 = 6*x+18
Move free summands (without x)
from left part to right part, we given:
$$18 x = 6 x + 33$$
Move the summands with the unknown x
from the right part to the left part:
$$12 x = 33$$
Divide both parts of the equation by 12
x = 33 / (12)
We get the answer: x = 11/4
