Answer:
Both Jared and Nicole are correct.
Step-by-step explanation:
This is because since y = x + 10 is one equation, the equation Jared uses, he substitutes for y into the other equation.
On the other hand Nicole finds x = y - 10 in the other equation.
We can get Jared's equation from Nicole's equation by making y subject of the formula. So,
x = y - 10
So, y = x + 10 which is Jared's equation.
We can also get Nicole's equation from Jared's equation by making x subject of the formula. So,
y = x + 10
So, x = y - 10 which is Jared's equation.
Since from one equations, we can get the other, and both equations for x and y are the same from both equations, that is, from y = x + 10, we get x = y - 10 and, from x = y - 10, we get y = x + 10,both Nicole and Jared are correct
