WEEK SIX:  Solving Equations

1)  Solve this equation:  9x + 6 = 12x - 3

          x = 3   

2)  Combine like terms:  5a + 7b - 2a + 10 - 5b

           3a + 2b + 10

WEEK TWO:  Algebraic Expressions & Integers

    1)  Write an expression to match this verbal phrase: "Seven less than the product of nine and a number."

           The expression is: "9x - 7" (you can use any letter you want, though.)

    2)  Evaluate this expression when x = 4 :  3(x-2) + 4x

           3((4)-2) + 4(4) =

              3(2) + 4(4) =

                6 + 4(4) =

                6 + 16 = 22       

    3)  What is the difference between an expression and an equation?

           An expression does NOT have an equal sign.  An equation DOES have an equal sign.

    4)  10 + (-7) = -3

    5)  12 - (-8) = 20

    6)  5(-2)(3) = -30
