Solve the inequality −4(x+4)>x+7. Give your answer as an interval.
Hint: The answer is not x<(-23)/5
−4(x+4)>x+7
−4x−16>x+7
−23>5x
x<−235
Why wouldn't it be x<-23/5?
Maybe it might prefer
(−∞,−235)
As an interval?
That's extremely strange
Are you sure you have the question correct?
(Maybe missing a minus sign or or something)
I just check with a math calculator and x<-23/5 is correct :\
