Answer:

x = 2

y = 4

Step-by-step explanation:

Since it gives you the "value" of y, just plug one of them into an equation:

y = x + 2

3x - 2 = x + 2

Now, subtract x from both sides:

3x - 2 = x + 2

-x         - x

__________

2x - 2 = 2

Then, add 2 to both sides:

2x - 2 = 2

    + 2  + 2

________

2x = 4

Finally, divide both sides by 2:

2x = 4

x = 2

Now to get y, just plug in 2 for x in an equation:

y = x + 2

y = 2 + 2

y = 4
