“Here the statement for equi-clearance is : 6x + 300 = 10x - 100. Now, by the rule, ‘Subtract the unknown on one side from that on the other etc.,’ unknown on the first side being subtracted from the unknown on the other side, the remainder is 4x. The absolute term on the second side being subtracted from the absolute term on the first side, the remainder is 400. The residual known number 400 being divided by the coefficient of the residual unknown 4x, the quotient is recognised to be the value of x, (namely) 100.”[¹]
