    Distribute where possible to get -3x - 9 = -3x - 3 -5 After that I'm sure you've got it.

    well, a real number is any irrational or rational number.

    Irrational number = a real number that cannot be expressed as a rational number ex. sqrt of 2 or PI Rational number = an integer or a fraction. 3/2 or 7

    Okay, that makes sence(: Soo, once I get -3x + -9 = -3x + -3 - 5, what would I do next? Thats where I get lost.

    Personally i would STOP and analyze that question, and realize the answer right there but we combine like terms -3x - 9 = -3x - 8 add 8 to each side -3x - 1 = -3x then add 3x to each side -1 = 0

    why i said we should analyze the question is because we can already see that the answer will be equal to 0 because the -3x's will cancel each other.
