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.

Abstract: Simultaneous nonlinear differential equations of growth of two variables x and y with time can be readily solved graphically by a method in which two directrices are used in the ...

Abstract: A simple and efficient graphical selective harmonic elimination method has been developed in this paper using which multiple harmonics can be simultaneously reduced even with two switchings ...
