The answer is 2/5

-1/5 + 3/5
(-1) + 3

This phrase, indicates that the 4 will be subtracted by something.

-Five times a number-
This would be: 5x

-Is equal to 11-
This is saying: =11

5x - 4 = 11            :First, add the 4 over to the 11
     +4     +4

(5x = 15)  ÷ 5         :Then, divide the whole equation by 5

Your final answer would be:
x = 3
