The first step in determining the solution to the system of equations, y=-x² - 4x-3 and y= 2x + 5, algebraically is
to set the two equations equal as-x² - 4x-3= 2x + 5. What is the next step?
Set y = 0 in y=-x² - 4x-3.
O Factor each side of the equation.
O Use substitution to create a one-variable equation.
O Combine like terms onto one side of the equa
