Exercise 9 Page 176

Substitute 7 into the given inequality and then simplify.

Yes, see solution.

We can determine whether n= 7 is a solution by substituting it into the inequality and simplifying using the order of operations.

n-3≤ 4

n= 7

7-3? ≤4

Subtract term

4≤ 4 ✓

Since 4 is less than or equal to 4, this means that n= 7 is a solution.
