Question

Is this correct?

question:
What is the solution of x - 2 < 4 and x + 4 > 7?

my answer:
x - 2 < 4 AND x + 4 > 7



x - 2 < 4

x - 2 + 2 < 4 + 2

x < 6



x + 4 > 7

x + 4 - 4 > 7 - 4

x > 3



The solutions were x < 6 and x > 3, so the solution to the AND inequality is 4 and 5.

Answer 1

Is there a reason you're only giving integer solutions...?

x < 6 and x > 3 is equivalent to 3 < x < 6

Answer 2

Oh yes, thanks for reminding me of that notation. Yes, 3 < x < 6 would be the same thing.
