    Let the cost of movie rental be x and video games be y
    4x + 8y = 61 ——– (1)
    2x + 3y = 24 ——– (2)

    (2) x 2:
    4x + 6y = 48 ———(2b)

    (1) – (2b):
    8y – 6y = 61 – 48
    2y = 13
    y = 6.5 —- sub into (1)

    4x + 8 (6.5)  = 61
    4x + 52 = 61
    4x = 61 – 52
    4x = 9
    x = $2.25

    Ans: Movie rental = $2.25 and Video Games rental = $6.50

    A) 4m + 8v = 61
    B) 2m + 3v = 24
    We’ll multiply equation B by -2
    B) -4m + -6v = -48 then we’ll add it to equation A
    A) 4m + 8v = 61
    2v = 13
    video game = 6.50
    we’ll input this into equation A
    A) 4m + 8 * 6.50 = 61
    4m + 52 = 61
    4m = 9
    movies = 2.25
