Question

Solve 4x > 36 and x + 5 < 8.
would it be 9 < x < 3?

Answer 1

x>9 and x<3 yes you are correct

Answer 2

don't write the answer as
9 < x < 3
because this is impossible (no number is both larger than 9 and less than 3 at the same time)
either the inequalities are to be solved separately and the answers are
x>9 and x<3 respectively
or as a system (if both are to be solved for the same x) the answer would be NO SOLUTION, because there is NO x such that
9 < x < 3
