    You are supposed to post new question in new threads....but I'll answer it anyways.

    1.) 7x+3=10x-9

    Add 9 to both sides:

    7x+12=10x

    Subtract 7x from both sides:

    12=3x

    Divide both sides by 3:

    x=4

    2.) 4x+6=6x-3

    Add 3 to both sides:

    4x+9=6x

    Subtract 4x from both sides:

    9=2x

    Divide both sides by 2:

    x=\frac {9}{2}
