    Simplify / frac{1}{2}/imath n (x+3) 2 1 ın (x+3) to / frac{/imath n (x+3) }{2} 2 ın (x+3)

    /frac{/imath n (x+3) }{2}-/imath nx=0 2 ın (x+3) -ınx=0

    2

    Add / imath nxınx to both sides

    /frac{/imath n (x+3) }{2}=/imath nx 2 ın (x+3) =ınx

    3

    Multiply both sides by 22

    /imath n (x+3) = / imath nx/times 2ın (x+3) = ınx*2

    4

    Regroup terms

    /imath n (x+3) = nx/times 2/imathın (x+3) = nx*2ı

    5

    Cancel / imathı on both sides

    n (x+3) = nx/times 2n (x+3) = nx*2

    6

    Divide both sides by nn

    x+3=/frac{nx/times 2}{n}x+3= n nx*2

    7

    Subtract 33 from both sides

    x=/frac{nx/times 2}{n}-3x= n nx*2 -3
