Question #N97
If $3x - 2y = 10$ and $x + 2y = 2$, what is the value of $x$?
A. 2
B. 3
C. 4
D. 6
Correct Answer is: B
To solve for x, we can add the two equations together. Notice that the y terms will cancel out: \begin{align*} 3x - 2y &= 10 \\ + (x + 2y &= 2) \\ \hline 4x &= 12 \\ \end{align*} Dividing both sides by 4, we get $x = 3$.
