           Combine like terms within the brackets.

            Use the distributive property to multiply out the brackets.

            The correct answer is D.

    6.               

           Multiply out the parentheses.

           To get all the x terms on the left side, you must subtract 5x from each side.

            In order to get all the number terms on the right side, subtract 10 from each side.

            The correct answer is A.

    9.               

           Get the x terms on the left side by subtracting  3x from each side.

            Get the number terms on the right side by subtracting 1 from each side.

            Finally, divide both sides by -1 (don’t forget to REVERSE the inequality sign!)

            The correct answer is D.

   13.      Simplify:        

The divides into the , leaving an  in the denominator.

            The correct answer is B.

   34.      Find the y-intercept:        .
