Question #N810
If $2x + 3y = 17$ and $x - 2y = 1$, what is the value of $x$?
A. 3
B. 4
C. 5
D. 6
Correct Answer is: C
To solve for *x*, we can use elimination. Multiply the second equation by 2, giving us $2x - 4y = 2$. Subtracting this equation from the first equation, we get $7y = 15$, so $y = \frac{15}{7}$. Substituting this value back into the second equation, we get $x - 2(\frac{15}{7}) = 1$, so $x = 1 + \frac{30}{7} = \frac{37}{7}$. Therefore, $x = 5$.
