first, isolate the radical
--
next square both sides to eliminate the radical
multiply both sides by 4
gather terms on one side
0=(x-5)*(x+3) factor
x=5, or x=-3
--
verify by substituting the answers into original equation
x=5:
2*3-1=5 check
x=-3:
2-1=1 does not equal -3 so x=-3 is not a solution
--
the answer is x=5
