    If x and y both equal 3, you substitute 3 for x and y in the equation. \[\frac{ 4(3)-(3) }{ 2(3)+(3) }\]

    Yeah the problems is this is the third time I did this and I did the whole equation thing and still got it wrong and it was the right way too. Sorry but math is my weakest subject and will always be ^.^

    Okay, so if you know that 18 is the base and 11 is the height, just fill in 18 as "b" and 11 as "h". Now, what does your formula look like?

    Great! So, now you multiply (11) * (18) and your answer from that will be divided by 2 because you're taking 1/2 of it. What answer do you get?
