2x - 32 + 4(3x - 2462) = 14x Does this have one solution, no solution or infinite solutions?

Solve 16 - 2n = -8 + 4(n - 3)

Solve 5x + 12 = 4x + 6

Solve $\frac{1}{2}x-7=\frac{1}{3}\left(x-12\right)$  

 $\left\{3x\ +4y\ =\ 36\ \ \ \ \ \ \ \ \ \ \ y\ =\ -\frac{1}{2}x\ +8\right\}$  

 $\left\{y=5\left(x-3\right)\ \ \ \ \ \ \ \ \ \ \ \ \ \ y=2x-6\right\}$  

 $\left\{y=-5\ \ \ \ \ \ \ \ \ \ \ \ \ 5x+4y=-20\right\}$  

 $-2x+4=-3x+4$
