Explanation:
This is a clear simultaneous equation.
In order to solve this, either the x's or the y's must be balanced. It does not matter which one you start with.
For this, I'll balance the y's:
Both y values can now be eliminated.
Now solve for x.
Put the value for x back into either equation to find y.
Rearrange to find y.
Divide both sides by -2.
