you have to put the variables on both sides the 4x stay positive because it was on the variable side, but 2x became -2x because it was on the exponent side. then you put 1 on the exponent side so it became negative you keep -5 because it Is on the exponent side. then you solve 4x-2x= 2x and -1-5= -6 then you divide 2x in both side and it is x=-3.
