Answer:
f(x)={x+5}/2-11
2x={x+5}-22
{-x+5}+2x=-22
{-x+5}=22-2x
{x+5}=22+2x
x+5=484+88x+4x^2
x+5-484-88x-4x^2=0
-87x+5-484-4x^2=0
-87x-479-4x^2=0
-4x^2-87x-479=0
4x^2+87x+479=0
x=-87+\- {87^2-4*4*479}/2*4
x=-87+\- {7569-4*4*479}/2*4
x=-87+\- {7569-7664}/2*4
x=-87+\- {7569-7664}/8
x=-87+\- {-95}/8
the square root of a negative number does not exist in the set of real numbers
x=R
*note: {xyz} means the square root*
