    Do the same to both sides so

    Figure out which side has the bigger x

    4x is bigger so get rid of the numbmers on the 4x side

    add 5 to both sides to get rid of the - 5 on the 4x side

    end up with 2x+5+5=4x+5-5

    2x+10=4x

    subtract 2x from both sides

    2x-2x+10=4x-2x

    10=2x divide both sides by 2

    5=x
