To solve this problem, simply substitute the values that have been given to you for both X and y. I believe in this question, it would be asking you to verify or check if the values of X and y are correct.
X = 1/4
Y = 1/2.
2x^2 + y = 5/8
2(1/4)^2 + 1/2 = 5/8
2(1/16) + 1/2 = 5/8
1/8 + 4/8 = 5/8
5/8 = 5/8.
1/2 = 4/8
2/16 = 1/8 in lowest terms.
