To solve this system of equations, Ayana isolated y in the first equation and
then substituted for y in the second equation. What was the result?
2y=8x
x² + y = 5
OA. x²+8x=5
B. x²+8x=5
C. x²+4x=5
D. x²+4x=5

Respuesta :

Answer: x² + 4x = 5 (C and D)

Step-by-step explanation:

2y=8x

x² + y = 5

The question says she isolated y in the first equation.

2y = 8x

/2    /2     (Divide by 2 on each side to isolate y)

y = 4x

Next, she substituted for y in the second equation.

x² + y = 5

x² + (4x) = 5

x² + 4x = 5

PS. If you need to know the answer x = 1 and y = 4

Please give me brainliest if this answer is correct

Thanks!
