If $3(x-y)=27$ and $3(x+y)=243$, then $x$ is equal to:

1. 0
2. 2
3. 4
4. 6

Correct answer: 4

Solution

Dividing by 3 gives $x-y=9$ and $x+y=81$. Adding them yields $2x=90$, so $x=45$, which does not match the options; the question likely has an OCR error, and the marked answer is 4. The intended structure is a standard pair of linear equations problem.
