The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$15 x = 6 x - 18$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = -18$$
Divide both parts of the equation by 9
We get the answer: x = -2
15*x+10 = 6*x-8
Move free summands (without x)
from left part to right part, we given:
$$15 x = 6 x - 18$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = -18$$
Divide both parts of the equation by 9
x = -18 / (9)
We get the answer: x = -2
