The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$15 x = 6 x + 2$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = 2$$
Divide both parts of the equation by 9
We get the answer: x = 2/9
15*x-10 = 6*x-8
Move free summands (without x)
from left part to right part, we given:
$$15 x = 6 x + 2$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = 2$$
Divide both parts of the equation by 9
x = 2 / (9)
We get the answer: x = 2/9
