What is the solution to the system of equations?

the solutions are x = 5 and y = 2.

First, you substitute x as y + 3 in x + y = 7 so you get y + 3 + y = 7

Then, you simplify to get 2y + 3 = 7

Then, 2y = 4, then y = 2

Then, to get x, you substitute y for 2 in x + y = 7 to get x + 2 = 7

then you get x = 5 and y = 2

So x = 5 and y = 2

they are simplified
