The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$5 x = 8 x + 18$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 18$$
Divide both parts of the equation by -3
We get the answer: x = -6
5*x+12 = 8*x+30
Move free summands (without x)
from left part to right part, we given:
$$5 x = 8 x + 18$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 18$$
Divide both parts of the equation by -3
x = 18 / (-3)
We get the answer: x = -6
