How do you solve $x - 2 y = 6; 3 x - 6 y = 18$ $x- 2y = 6;3x - 6y = 18$ ?

Any pair $(x, y)$ $(x,y)$ for which $y = \frac{x - 6}{2}$ $y=(x-6)/2$ will provide a solution for these equations (i.e. there is no single solution).

Explanation:

The two equations represent the same line; the second equation is simply the first multiplied by $3$ $3$
