Question

Please help im very confused. Will give medal
y = x + 4
y = −2x − 2

Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

Answer 1

they both equal y so then replace y in the 2nd equation with the 1st equation

x + 4 = -2x - 2

now you can solve for x.

when you get a value, substitute it into either of the original equations to find y.

Answer 2

Thank you!
