he 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 solutions of the system.

--Equations--
1)) Y^2 + 16 = x

2)) X^2 = y + 16

3)) 1 - 4y = 7x

4)) (2x)^2 = y + 16

5)) 7y - 1 = 4x

6)) 4y - 1 = 7x
