8x + y = 20

mathstudent55 · Answer

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

anonymous · Answer

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

usukidoll · Answer

$$y=x^2-2x+4$$
$$8x+y=20 $$

we can use substitution.... place  the y from the first equation into the second equation.. and solve for x
