Not illustrated. 1895 Excerpt: ...3x-y-.-=--(1),-I(2-5) = y (2). Clear of fractions. Thus from(1), 42x-2y+10 = 28x-21; /. Ux-2y =-31 (3). From (2), 9y +12-10x + 25 = 15//;.-. 10x + 6y = 37 (4). Eliminating y from (3) and (4), we find that 14 x =---. 13 Eliminating x from (3) and (4), we find that "26 107. Simultaneous equations may often be conveniently solved by considering-and-as the unknown quantities. x y Example. Solve 8_? = 1 (1), x y M = 7 (2). x y Multiply (1) by 2 and (2) by 3; thus 16_18 = iJ x y MS. a, X y adding,--= 23; x multiplying up, 46 = 23x;;. x = 2; and by substituting in f 1), i,-3. H.A. v 108. In order to solve simultaneous equations which contain two unknown quantities we have seen that we must have two equations. Similarly we find that in order to solve simultaneous equations which contain three unknown quantities we must have three equations. Rule. Eliminate one of the unknowns from any pair of the equations, and then eliminate the same unknown from another pair. Two equations involving two unknowns are thus obtained, which may be solved by the rules already given. The remaining unknown is then found by substituting in any one of the given equations. CHAPTER XIV. Problems Leading To Simultaneous Equations. 110. In the Examples discussed in the last chapter we have seen that it is essential to have as many equations as there are unknown quantities to determine. Consequently the statement of problems which give rise to simultaneous equations must contain as many independent conditions, or different relations between the unknown quantities, as there are quantities to be determined. Example 1. Find two numbers whose difference is 11, and onefifth of whoso sum is 9. Let x be the greater number, y the less; then x--2/ = ll (1). Also =9, or a+y=45 (2). By addition 2z=5...
