    Elimination method
    1) 5r-6s=-10
    6r+5s=49

    2) 1/3x + 1/1y=2/3
    2/3x + 3/5y=1/5

    3) 5x+3y=-12
    6x-3y=-54

    4) p=47+q
    8p=6q+404

    Substitution method

    1) x+y=5
    y=x-3

    2) r-45=0
    6r-5s=133

    3) 6x+3y=-36
    -7x+y=60

    System of equation by graphing:

    1) y-2x=0
    y=4x-1
