Ok I will be posting a lot of questions in this thread for the sake of trying not to clutter up the forums... so if you get the stuff I am talking about please stick around and help me out... I would love you forever... :p

Ok so right at the moment I am having trouble with this problem here I am normaly OK at setting them up but I can figure this one out :eek:

A larger number minus a smaller number is 18. The larger number is three times the smaller. Find the numbers.


I am also having trouble as to how to do these kinds of problems all together XD...
3/4q-7=8

and like...
c-5/4=3

and las but never least
h/3-4=13


I am failing math guys ANY help would be luffed!:o

Lets start with the number problems.
3/4q-7=8
just add 7 to each side
3/4q=15
mulitply by 3/4
and q=11.2

c-5/4=3
add 5/4 to 3
c=4 1/4

h/3-4=13
multiply by 3-4
h=3(3-4)
distribute the 3
h=9-12
then subtract
h=-3

now the word problem

A larger number minus a smaller number is 18. The larger number is three times the smaller. Find the numbers.

set it up
x-y=18 and x=3y
3y-y=18
subtract
2y=18
divide
y=9
x-9=18
add 9 to each side
x=27
small number 9, large number 27

1. Let the numbers be represented by 3x and x. Then, 3x - x = 18 ; 2x = 18 ; x = 9 and 3x = 27 so your numbres are 27 and 9.

2. Do you mean (3/4)q - 7 = 8 or 3/(4q) - 7 = 8? Is the q in the numerator or the denominator? It's hard to tell from the way you typed the question and that'll make a big difference.

3. Same uncertainty here ; did you mean c - (5/4) = 3 or (c - 5)/4 = 3?

4. h/3 - 4 = 13
h/3 = 17
h = 51
