Answer:
3
Explanation:
You need to look at the inequalities on the right to find which one x=3 satisfies
Testing x =3 in the Inequalities
can't be first because 3 is not between -1 and -2
can't be second because 3 is not between -1 and 3
last one x is greater than or equal to 3, which is true
Therefore you sub x=3 into the equation next to that
6-x
6-3 = 3
