Answer 1

(2, 3)

Explanation:

Since y = 5 - x, we can substitute y in the first equation with 5 - x.

• 2x - (5 - x) = 1

Then we can simplify.

• 2x - (5 - x) = 3x - 5 = 1

After that, we can isolate x. We do this by adding the 5 to both sides which evens out the -5 into 0.

• 3x + 0 = 6 or 3x = 6

Now, we can divide it all by three to get a singular x value.

• x = 2

Now that we have our x value, we can plug it into either original equation to find our y value.

• y = 5 - x or y = 5 - 2 or y = 3

Since we now know that x = 2 and that y = 3, we can write them as an ordered pair.
