What is the Solution to -54/x = -6?
A. X = 9
B. X = -6
C. X = 6
D. X = 9
I do not really understand this question can someone help me? (Not asking for a answer)

And whats the difference between |-8| and 8? Arnt they the same?

One last question i don't fully understand

9m = -63?
A. M= -57
B. M= -7
C M= 7
D M = 57

Again I am not asking for a answer i just need help understanding

  1. Treat it as you always do fractions. Multiply by the denominator to clear the fraction:

    -54/x = -6
    -54 = -6x
    Now it's a cinch, right?

    |x| is the "size" of x, regardless of whether it is positive or negative. It is defined as
    |x| = x if x >= 0
    |x| = -x if x < 0
    So,
    |8| = 8
    |-8| = -(-8) = 9
    8 and -8 are both the same distance from zero.

    9m = -63
    just divide by 9
    m = -7
