Its step 2 my guy.....................................
17 over 9, Square root of 6, Square root of 15, Square root of 30, 33.
If you make 17 over 9 into a mixed number, you get 1 and 8/9. the square root of 6 is between 2(square root of 4) and 3(square root of 9). The square root of 15 is between 3 and 4(square root of 16). The square root of 30 is between 5(square root of 25) and 6(square root of 36)... then 33 is an outlier.
substitute 7 for y then solve for x
x = 2/3
