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.

Before starting this guide, it may be helpful to read the guide from M1 on coordinates and graphs. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same ...

with B * = I- B. This requires that one of the preceding equations be solved for P t. Solving the second equation for P t yields You can estimate the intercepts of a system of simultaneous equations ...
