**PsyDAG**, Monday, January 3, 2011 at 10:15am2P + 3J = 5.25

3P + 2J = 6.00

Multiply first equations by 3 and second by 2.

6P + 9J = 15.75

6P + 4J = 12.00

Subtract second from first.

5J = 3.75

Solve for J and insert that value into either original equation to find P. To check, put both values into the other equation.
