X= y^2 - 1 2x - y = 4 which of the following equations could be the result of using substitution to solve the system? 2y 2 - y - 5 = 0 2y 2 - y - 6 = 0 2y 2 - 2y - 5 = 0

 The correct option is (B)

Step-by-step explanation:  We are given the following system of equations :

We are to find the equation that could be the result of using substitution to solve the above system.

Substituting the value of x from equation (i) in equation (ii), we get

Thus, the required equation is

Option (B) is CORRECT.
