**Difficulty:** Easy

**Category:** Heart of Algebra / Systems of Linear Equations

**Strategic Advice:** When solving a system of linear equations, always look at the coefficients of the variables to decide on a strategy. Here, because you're looking for the value of *y*, subtracting the first equation from the second equation will get you to the answer the quickest (because the *x*'s will be eliminated and you'll be left with *y*).

**Getting to the Answer:** Rewrite the equations with the second equation on top. Then, carefully subtract:

The correct answer is (A).
