Hello everyone, I am doing some Algebra 2 work and I have two system equation problems that I am stuck on from a worksheet.

"SOLVE SYSTEM EQUATION:"

Here is the first one that I am stuck on:

Y = 3X + 1

Y = 3X + 5

------------------------------------

Here is the second one:

Y = 7 - 2X

2X + Y = 7

------------------------------------

Thank you in advance, I appreciate any help given.
