    3. Prof Halleck is teaching 2 sections of quantitative reasoning with a total of 64 students. If one section has 8 more students than the other, how many students are in each section? To get credit you must define a variable and create a linear equation.

    x=y+8
    x+y=64

    y+8+y=64
    2y+8=64
    2y-8=64-8
    2y=56
    y=56

    y=28 (64-28=36)

    There are 28 students in one section and 36 in another.
