    1st distribute the 3 to the 2x and the 5 ... you get 6x+15=3

    then subtract 15 from each side ... you get 6x=-12

    then divide each side by 6 ... and you get x=-2

    Alright, it looks like the first thing you need to do is divide both sides of the equation by 3 to get rid of those parenthesis, which should leave you with 2x+5=1

    Your next step should be to try and get the x variable alone without adding anything to it, so we need to subtract the 5 from both sides of the equation leaving you with 2x = - 4

    Finally, you need to get x alone without any coefficients, so we should divide both sides of the equation by 2, leaving us with x = - 2, which should be your answer.
