use the substitution method to solve the system $y = -3$, $y = 2x + 1$. (1 point)

Explanation:

Step1: Substitute $y=-3$ into the second equation

$-3 = 2x + 1$

Step2: Isolate the term with $x$

$2x = -3 - 1$
$2x = -4$

Step3: Solve for $x$

$x = \frac{-4}{2} = -2$

Answer:

$x=-2$, $y=-3$ (the solution is the ordered pair $(-2, -3)$)
