  1. x = 4, y = 2

    2. 3x + 3 = 15
        3x = 12
        x = 4 <==

    3. 4a + 2 > = 12
        4a > = 10
        a > = 5/2 (or 2.5)
        answer is {2.5,3,3.5}

    4. 2.25(2) + 7.25(3) + 11.25 > = 35
        4.50 + 21.75 + 11.25 > = 35
         37.50  > = 35...yes, because total is $ 37.50

    5. 18(2/3) + 4 > 18
         12 + 4 > 18
         16 > 18........FALSE
