Next, you eliminate y by multiplying the bottom equation by negative 1.
Then, your answer is:
Next, you combine like terms. Your answer is:
5x=15. (The y’s cancel out, because 3 is the opposite of negative 3.)
Divide both sides by 5, leaving you with x=3.
Lastly, you substitute x into the top equation. You get:
Subtract 3 from both sides, leaving you with 3y=9.
Divide both sides by 3, so y=3. The final answer is (3,3).
