2p+3q=3

Answer
I am more interested in the method and that you understand how this
is done than the actual answer.
Note the q's have the same coefficient in both equations.
When that happens, just subtract one equation from the other.
2p + 0 = 6
p = 3
now sub that into either of the two equations. You MUST get the
same result. I will let you finish it.
