Question #N553
If $2x + 3y = 12$ and $x - y = 4$, what is the value of $x$?
A. -2
B. 2
C. 3
D. 4
Correct Answer is: D
To solve for $x$, we can use the elimination method. Multiplying the second equation by 3, we get $3x - 3y = 12$. Adding this equation to the first equation, we get $5x = 24$, or $x=\frac{24}{5}$ = 4.8, which is closest to 4.
