**Reiny**, Sunday, January 6, 2013 at 11:19pm1st times 8 ----> p + 6q = 56 or p = 56-6q

2nd times 2 ---> 3p - 2q = 8

3(56-6q) - 2q = 8

168 - 18q - 2q = 8

-20q = -160

q = 8

then p = 56-6(8) = 8

**p= 8 and q = 8**

Notice how for both of your last two posts, I got rid of fractions to make the equations much more manageable.
