Answer: (3, 5]

Explanation:

3w-3<=12 and 2w-1>5

3w-3+3<=12+3 and 2w-1+1>5+1

3w<=15 and 2w>6

3w/3<=15/3 and 2w/2>6/2

w<=5 and w>3

3<w<=5 ==> (3, 5]

Parentheses are notated for non-inclusion(3 isn't included in the solution) and brackets are notated for inclusion(5 is included in the solution).
