well 2 ways elimination method or substitution method
i find elimination method fastest and easiest
subtract y and add 2 to both sides
.
imma subtract the equations
add lik terms
divide by 4
.
substitute for x
multiply
add y and 1 to both sides
add

I have no idea how you would solve it. All I can tell you is how I would solve it, but bear in mind that there are at least 3 other equally valid ways to do it.
Add 3 to both sides of the first equation giving you an expression in 
that is equal to 
. Substitute this expression in place of in the second equation. You will now have a single variable equation in . Collect terms and solve for . Take this newly discovered value for and substitute it back into the first equation giving you a single variable equation in . Solve it.
You now have a value for and a value for . Substitute both values into each of the original equations to check your work. If you have done the arithmetic correctly, then in each case the result is a true statement.
Given a successful check step, form the ordered pair )
with the values determined. Your solution set consists of the single element of the ordered pair just formed.
