Question

Choose the correct ordered pair.

X+ y = 3
y=8

A. (5,8)
B. (11,8)
C. (-5,8)
D. (-11,8)​

Answer 1

So,

`x+y=3\Rightarrow y=3-x`

Then,

`8=3-x\Rightarrow x=-5`

The ordered pair is therefore,

`C(-5,8)`

Hope this helps.

Answer 2

Answer: C

Explanation:

plug in y=8 to

x+y=3

x+8=3

x=-5

There is no need to look at the other answer choices since they do not have x equaling to -5.
