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 $A$, $A_2$ represents the second column of $A$ and $A_3$ represents the third column of $A$. Determine values of $x_1$, $x_2$ and $x_3$ so that $$x_1 A_1 + x_2 A_2 +x_3 A_3 = b$$ .
