Answer: 31
Step-by-step explanation:
179 - 148 = 31
You would do pemdas or (), exponits, *, division, +,-
All you need to do is divide -1/2 onto the other side.
-1/2x<-12
-12/ (-1/2)= 6 (a negative and a negative equals a positive)
Also, since you are dividing a negative, you flip the sign.
x>6
I hope this helps!
