Question

What are the solutions to the following system of equations? Select the correct answer below.

y = x2 − 2x + 4
8x + y = 20

Answer 1

If you are given choices, substitute each choice in both equations. The choice that makes both equations true is the answer.

Answer 2

from second y=20-8x ,plug in first and find the value of x and then y.

Answer 3

\[y=x^2-2x+4\]
\[8x+y=20 \]

we can use substitution.... place the y from the first equation into the second equation.. and solve for x
