Question

Which order pair is a solution to the system of linear equations -4+y=8 and x-5y=17?

Answer 1

Hello!

To find this ordered pair, we solve for x and y and put them together in an ordered pair.

-4+y=8

x-5y=17

Let's solve the first equation for y.

y= 12

Now, let's plug 12 into the second equation for y.

x-5(12)=17

x-60=17

x=77

Therefore, our ordered pair is (77,12)

I hope this helps!

Answer 2

(77,12)

Explanation:

`-4+y=8`

`x-5y=17`

We need to solve for x and y

USe substitution method, we solve the first equation for y

`-4+y=8` , add 4 on both sides to get y alone

`y=12`

Now we plug in 12 for y in the second equation and find out x

`x-5y=17`

`x-5(12)=17`

`x-60=17`

Add 60 on both sides

`x= 77`

The ordered pair is (x,y). our x=77 and y=12

So ordered pair is (77,12)
