Simple...
you have: 15x+2=17
Isolate the variable (x)-->>>>
15x+2=17
-2 -2
15x=15
x=1
To check it-->>>
15(1)+2=17
17=17
Thus, your answer.
Find total number of integers.
Find how many integers is divisible by 2.
Eliminate even numbers.
11, 13, 15,..., 57, 59
This array contains 51 - 26 = 25 numbers.
Eliminate numbers before the first number divisible by 3 and after the last number divisible by 3.
15, 17, 19,..., 55, 57
This array contains 25 - 3 = 22 numbers.
Now we should eliminate numbers divisible by 3: 15, 21, 27...
There are 8 such numbers.
Therefore, there are 25 - 8 = 17 numbers that <span>can be evenly divided by neither 2 nor 3</span>
I think it is b because to me it makes the most sense
