Question #N483
If \(2x + 3y = 10\) and \(x - y = 2\), what is the value of \(x + y\)?
A. 2
B. 3
C. 4
D. 5
Correct Answer is: C
To solve for x + y, we can add the two equations together. Notice that the y terms will cancel out. The result is: (2x + 3y) + (x - y) = 10 + 2. Combining like terms, we get 3x + 2y = 12. Since we are looking for x + y, we can't simplify further.
