Use the substitution method to solve the system y=−3 , y=2x+1 .(1 point) ()
Since y is given as -3 in the first equation, we substitute -3 for y in the second equation:
-3 = 2x + 1
Then, we solve for x:
2x = -3 - 1
2x = -4
x = -2
Therefore, the solution to the system of equations is x = -2 and y = -3.
