The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 2 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 9$$
Divide both parts of the equation by -5
We get the answer: x = -9/5
-3*x-9 = 2*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 2 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 9$$
Divide both parts of the equation by -5
x = 9 / (-5)
We get the answer: x = -9/5
