17=15k-2 what does k equal? 7 thought it was 3 and 2/5 but ichecked and icant get the right answer

Add 2 to both sides

You get 19=15k

Divide 15 on both sides and get 19/15=k

19/15 = 1 and 4/15

It is 1 and 4/15 because 15 goes into 19 1 time. So the 1 leads. It leaves a remainder of 4 which becomes the numerator. You keep the same denominator of 15.

17+2=15k

19=15k divide both by 15 k = 1.27
