Answer:

x = 3 and y = 1

Explanation:

To solve this system of equations, we can use substitution or elimination. Here's how to use the substitution method:

1. Solve one of the equations for one of the variables. For example, we can solve the first equation for x:

x = y + 2

2. Substitute this expression for x into the second equation and solve for y:

3y + 2(y + 2) = 9

3y + 2y + 4 = 9

5y = 5

y = 1

3. Now that we know y = 1, we can substitute this value back into either equation to find x. Let's use the first equation:

x - y = 2

x - 1 = 2

x = 3

Therefore, the solution to the system of equations is x = 3 and y = 1. We can check our answer by substituting these values into both equations and verifying that they are true.
