Create an equivalent system of equations using the sum of the system and the first equation.

−5x + 4y = 8
4x + y = 2


A) −5x + 4y = 8
9x + 5y = 10


B) −5x + 4y = 8
−x + 5y = 10


C) −5x + 4y = 8
9x + 5y = 2


D) −5x + 4y = 8
−x + y = 10

Respuesta :

Answer:

B) {-5x + 4y = 8

{-x + 5y = 10

Step-by-step explanation:

Add like it said, and you will see your answer.

Answer:

Option B

[tex]-5x+4y=8[/tex]

[tex]-x+5y=10[/tex]

Step-by-step explanation:

We are given that

System of equations

[tex]-5x+4y=8[/tex]

[tex]4x+y=2[/tex]

We have to find an equivalent system of equations using sum of system and first equations

Sum of system of equations

[tex]-5x+4y+4x+y=8+2[/tex]

[tex]-x+5y=10[/tex]

Therefore, option B is true.
