here is another method since this is a simple 2 equations and 2 variables x + 3y = 7 2x + 6y = 9 solve each equation for y y = (1/3)*x+7/3 y = (1/3)*x+3/2 as you can see it will be in the y=mx + b form the m aka slopes are the same. which means they dont meet ever. and the bs are different. therefore no solution. When Ms are same and Bs are different.

If you're familiar with determinants, you can calculate \[\begin{vmatrix} 1 & 3 \\ 2 & 6\end{vmatrix} = (1)(6)(3)(2) = 0,\] so there is no solution.
