Let me do some algebra, it will be self explanatory.
[tex]ax-cx=d-b[/tex]I have basically moved cx to the left, and b to the right, now let me do more algebra
[tex]x(a-c)=d-b[/tex][tex]x\text{ =}\frac{(d-b)}{(a-c)}[/tex]Now the Second method is the graphing the equation and finding the values of x, that follow the graph.
[tex]y=mx+b[/tex][tex]y(x)=x(a-c)-d+b[/tex]
