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
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
