  • 4) 0=-5n-2n
    0=-7n
    n=0
    5) 6r-1+6r=11
    12r-1+11
    12r=12
    r=1
    6) r+11+8r=29
    9r=18
    r=2
    7) -10=-14v+14v
    -10=0
    no solution because the sides are not equal
    10) a-2+3=-2
    a+1=-2
    a=-3
    11) 18=3(3x-6)
    18=9x-18
    36=9x
    9x=36
    x=4

    hope i could help
