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.
SOME years ago you published some interesting communications in regard to the graphical solution of cubic and quartic equations (vol. lxi. p. 55, vol. lxiii. pp. 515 and 609, vol. lxiv. p. 5). The ...
