Possibility 1
You want to find the value of #x# for which #g(x) = 1/3# given #g(x) = 2x-5#
#color(white)("XXXX")##2x-5 = 1/3#
#color(white)("XXXX")##6x-15 = 1#
#color(white)("XXXX")#x = 16/6 = 8/3#

Possibility 2
You want to find the value of #g(x)# when #x=1/3#
#color(white)("XXXX")##g(1/3) = 2(1/3)-5#
#color(white)("XXXX")##color(white)("XXXX")##= 2/3 -5#
#color(white)("XXXX")##color(white)("XXXX")##=- 4 1/3#
