The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Divide both parts of the equation by (-x + 2*sqrt(2))/x
We get the answer: x = 5 + 2*sqrt(2)
sqrt(2)^(3)-x = -5
Expand brackets in the left part
sqrt2^3-x = -5
Divide both parts of the equation by (-x + 2*sqrt(2))/x
x = -5 / ((-x + 2*sqrt(2))/x)
We get the answer: x = 5 + 2*sqrt(2)
