The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$0 = 5 x + 36$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 36$$
Divide both parts of the equation by -5
We get the answer: x = -36/5
9 = 5*(x+9)
Expand brackets in the right part
9 = 5*x+5*9
Move free summands (without x)
from left part to right part, we given:
$$0 = 5 x + 36$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 36$$
Divide both parts of the equation by -5
x = 36 / (-5)
We get the answer: x = -36/5
