    2P + 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.
