The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 6 x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = -2$$
Divide both parts of the equation by -11
We get the answer: x = 2/11
13-(5*x+11) = 6*x
Expand brackets in the left part
13-5*x-11 = 6*x
Looking for similar summands in the left part:
2 - 5*x = 6*x
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 6 x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = -2$$
Divide both parts of the equation by -11
x = -2 / (-11)
We get the answer: x = 2/11
