The relationship between two numbers is described below, where x represents the first number and y represents the second number. The square of the first number is equal to the sum of the second number and 16. The difference of 4 times the second number and 1 is equal to the first number multiplied by 7. Select the equations that form the system that models this situation. Then, select the solution(s) of the system. Equations Solutions
y2 + 16 = x (2x)2 = y + 16 (1,15) (5,9)
x2 = y + 16 7y - 1 = 4x (2,-12) (8,48)
1 - 4y = 7x 4y - 1 = 7x (4,-7) (9,3)
