Question

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

Answer 1

B) {-5x + 4y = 8

{-x + 5y = 10

Explanation:

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

Answer 2

Option B

`-5x+4y=8`

`-x+5y=10`

Explanation:

We are given that

System of equations

`-5x+4y=8`

`4x+y=2`

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

Sum of system of equations

`-5x+4y+4x+y=8+2`

`-x+5y=10`

Therefore, option B is true.
