Question

Use the substitution method to solve the system y=−3 , y=2x+1 .(1 point) ()

Answer 1

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.
