How would you solve the problem below using subsitution method?

7x - 2y = 5
x = y


If you could explain and show this step by step, it would help a lot.

How would you solve the problem below using combination method?

3x - 2y = 12
-3x + 8y = -6


If you could explain and show this step by step, it would help a lot.



Thank you.
