Solve A x= b by finding coefficients for the columns of A which show b lies in their span.

When solving $$Ax=b$$ the solution $x$ can be determined by determining the linear combination of the columns of A which equal b. In the interactive cell below $A_1$ represents the first column of A while $A_2$ represents the second column of A. Determine values of $x_1$ and $x_2$ so that $$x_1 A_1 + x_2 A_2 = b$$ .
