Answer:
q = 6/13, p = 35/13
Step-by-step explanation:
3p + 2q = 9
2p - 3q = 4
_________ (subtract the two equation from each other.)
p + 5q = 5
p = 5 - 5q
2(5 - 5q) - 3q = 4 (substitute value of p into equation)
10 - 10q - 3q = 4
10 - 13q = 4
-13q = -6
<u>q = 6/13</u>
3p + 2(6/13) = 9 (substitute value of q into equation)
3p + 12/13 = 9
3p = 105/13
<u>p = 35/13</u>

Answer:
x=-12
Step-by-step explanation:
Start by getting all of the x values on one side and other to the other.
1/3x-3/4x=1+4
Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.
4/12x-9/12x=5
-5/12x=5
x=5*(12/-5)=60/-5=-12
x=-12
