Simultaneous equations like đť’š = 2đť’™ - 1 and đť’š = đť’™ + 1 can be represented graphically. To solve the equations graphically, the two lines đť’š = đť’™ + 1 and đť’š = 2đť’™ - 1 are drawn on the same diagram.
The unknown values in an equation could be the individual costs of a smoothie and a banana when the combined cost is known. Simultaneous equations can be useful when running a business. Watch the ...
