  1. It's not an equation. There's no equal sign.

    3(x - 3) + 3x
    3x - 9 + 3x
    9x - 9

  2. -2( y- 3) = 2y -6
    i figured that out can you help me on this one i don't know wht it means when people say how many solution does this have can u explain it to me

  3. Work it out.
    -2( y- 3) = 2y -6
    -2y - 6 = 2y - 6
    etc. How many answers can you get for y? I get y = 4 so it has one solution.

    Here is another example but you can get more than one answer.
    X^2 + 5x + 6 = 0 and solve.
    (X+2)(X+3) = 0
    There are two solutions to this one.
    X+2 = 0 so X = -2
    X+3 = 0 so X = -3

  4. Go to Google and type in "how many solutions are there to an equation" without the quotation marks. I can't post the URL.
