The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$5 x = 9 x + 22$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = 22$$
Divide both parts of the equation by -4
We get the answer: x = -11/2
5*(x-(22/5)) = 9*x
Expand brackets in the left part
5*x+5*22/5) = 9*x
Move free summands (without x)
from left part to right part, we given:
$$5 x = 9 x + 22$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = 22$$
Divide both parts of the equation by -4
x = 22 / (-4)
We get the answer: x = -11/2
