3x+5x+21=y
3x+5x=8x
8x+21=y
-21 -21
8x=y-21
8x÷8=x
y-21÷8=y-2.625
x= -2.625 + 0.125 y
I think that is right... :)
The sign would be negative because there is an odd number of negatives. If there were an even number of negatives it would be positive.
Multiply -5 by -1
The answer would be -5/2
Answer:
98
Step-by-step explanation:
ABSOLUTE BRACKETS MEAN ABSOLUTE VALUE- this means that negatives will come out as positives since their absolute values are the same. So |-9| is just 9.
|-81-17| (apply the rule I just gave you)
|81+17|
98
