    #3-8 is simply halving or doubling.


    9. 2(2x-3) = x+9
    4x+6=x+9
    3x=15
    x=5
    10. 2(x+19)=x+29
    2x+38=x+29
    x=-9
    11. 2(x+2)=3x-8
    2x+4=3x-8
    x=12
    12. 2(x-3)=x+6
    2x-6=x+6
    x=12
    13.2(x+2)=x+10
    2x+4=x+10
    x=6
    LN=6+10=16
    14. 2(x-2)=x+3
    2x-4=x+3
    x=7
    RQ=7-2=5
    15. 2(2x-14)=x+2
    4x-28=x+2
    3x=30
