v2.c17.s12.1

To solve a linear equation involving more than two unknowns the usual Hindu method is to assume arbitrary values for all the unknowns except two and then to apply the method of the pulveriser. Thus Brahmagupta remarks, "The method of the pulveriser (should be employed), if there be present many unknowns (in an equation)."² Similar directions have been given by Bhâskara II and others.³
