    Post Math Homework

    Help me do this.
    No answers please.
    Just tell me basically what to do and stuff.


    1) Solve and check each of the following.
    a) 0.4x = 5.58 – 0.2x
    b) 7.2 + 2.3x = 3.2x
    c) x/6 – 9/2 = 2x/3
    d) 3/2 m = m + 7
    e) (x – 3)/2 = 10
    f) 1.4m = 1.5m – 0.57

    2) Solve and check each of the following.
    a) (1/2)x – 1 = (1/4)x + 3/4
    b) 1.3m + 64.2 = 2.7m + 12.82
    c) 5n – 6.4 = 3n + 2.6
    d) (1/2)n – 3 = 4 + (2/3)n
    e) (1/4)x + (1/3)x = x + 1/6
    f) 1.2m – 17 = 8 + 0.7m

    And note that non-CAS GDCs don't show how an equation is solved (unless you're using the step functions from TI's later calculators) and neither would that really help with such simple examples.
