We solving a system of equations Jerry found out why equals X PlayStation for one equation is said to express team for why in the other equation Nicole found at eight equals Y - 10 for the same equation Y - 10 for eggs 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.
