Solve the linear equation $11x - 4 - 8x = 2(x + 4) - 2x$ for $x$.
A$x = 4$
B$x = -4$
C$x = 12$
D$x = 0$
Answer & Solution
Correct answer: A. $x = 4$
Combine like terms on the left: $11x - 8x - 4 = 3x - 4$. Expand the right side: $2(x+4) - 2x = 2x + 8 - 2x = 8$. So $3x - 4 = 8$, giving $3x = 12$ and $x = 4$. Substitute back to verify: both sides equal 8.
