Add 3 on both sides

8y - 3 + 3 = 13 + 3

8y = 13 + 3

8y = 16

Divide 8 on both sides

8y/8 = 16/8

y = 16/8

y = 2

y = 2

To prime factorization would be A: 2 X 3 X 5 X 7

Because if your do 2 X 3 it would be 6

Then you do 5 X 7 it would be 35

And 6 X 35 would be 210

AND THAT IS FACTORING THE PROBLEM
