When solving a system of equations, Jared found y = x +
10 for one equation and substituted x + 10 for y in the
other equation. Nicole found x = y - 10 for the same
equation and substituted y - 10 for x in the other
equation. Who is correct? Explain.

Both Jared and Nicole are correct. You can solve for either variable and use the equivalent expression to create a one-variable equation. Then you can solve. Jared would have created a one-variable equation that can be used to solve for x, whereas Nicole would have created a one-variable equation that can be used to solve for y.

Step-by-step explanation:

Jared is correct because if you substitute a random number in for x 2 for example

2+10=12

2-10 doesn’t =12
