Question

Solve this system of equations using elimination. Write your answer as an ordered pair,

5x-2y = 10
4x + 2y = 8

Answer 1

the answer is C

Explanation:

Answer 2

Solving the system of equations using elimination method, we get x=2, y=0

The ordered pair is: (2,0)

Explanation:

We need to solve the system of equations using elimination method.

`5x-2y = 10\\4x + 2y = 8`

Let:

`5x-2y = 10--eq(1)\\4x + 2y = 8--eq(2)`

Add both equations to eliminate y and find value of x

`5x-2y = 10\\4x + 2y = 8\\------\\9x=18\\x=(18)/(9)\\x=2`

We get value of x=2

Now, finding value of y by putting value of x in eq(1)

`5x-2y=10\\Put\:x=2\\5(2)-2y=10\\10-2y=10\\-2y=10-10\\-2y=0\\y=0`

We get value of y= 0

Solving the system of equations using elimination method, we get x=2, y=0

The ordered pair is: (2,0)
