SOLUTION: Solve using the multiplication principle first. Then use the elimination method:
7p+5q=2 8p – 9q =17
can you use a high number to multiply like 45 to cancel out the q's help!

You can put this solution on YOUR website! Solve using the multiplication principle first. Then use the elimination method:
7p + 5q=2
8p – 9q =17
can you use a high number to multiply like 45 to cancel out the q's help!
------------
Is 45 a "high number?" What about 5,678,932 ?
-------------
7p + 5q=2 Multiply by 9
8p – 9q =17 Multiply by 5
------------
63p + 45q = 18
40p - 45q = 85
---------------- Add
103p = 103
p = 1
--------
You can finish it.
