The number is the same but the placement is different. How can we determine what the transformation is just by the placement?

In this video we are going to work through 5 different examples where we will simplify the higher root of a radical ...

Simultaneous equations like 𝒚 = 2𝒙 - 1 and 𝒚 = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same diagram.
