6(y – 7)
Explanation:
743, 437, 473, 347 are all the 3-digit odd numbers that can be created using those tiles
Sub in what X and y are:

. Solve the exponents (if the exponent is 2 multiply the whole number by itself twice, if it were 3 you would multiply the whole number by itself three times): 3·3=9, 3·3=9: 9(9)= 81. :)
One of them can be finding the x intercept which the answer would be x= 5
