Solve the equations: -6 x-2=2(-3 x-1)

Solution: x =

Enter NS for no solution or IS for infinite solutions

Solve the system of equations by graphing: $\displaystyle {\left\lbrace\begin{array}{cc} {y}=&-{6}{x}-{2}\\{y}=&{2}{\left(-{3}{x}-{1}\right)}\end{array}\right.}$
Graph will "snap to" every 1 points

How many solutions does this system have? And what is the point of intersection if there is a single solution?
