    Hello Red Ruby!

    Thank you for asking us your question!

    In this case, you can solve this as a system of equations. You can assume that y = y to compare both equations as below:

    $$ y = y \Rightarrow 2x - 1 = (x+6)^2 + 11 $$

    You can then isolate all the equations on one side to have an equation following the format \( 0 = ax^2 + bx + c \). You can then find the value for \( b^2 - 4ac \) to determine of the system will admit one, two or no solutions.

    You can follow the link below to look at similar examples:
