These examples will help you. Consider the system of two equations (i) and (ii) underneath as: 2x - 3y = 8 ........          (i). 3x + 4y = -5 ........         (ii). Step 1 Multiply (i) with 3 6x - 9y = 24 ......          (iii). Multiply (ii) via 2 6x + 8y = - 10 ......        (iv). Subtract iii from iv. 17y = -34 .........            (v).  y = -2 Step 2 Multiply (i) via 4 8x - 12y = 32 .......       (vi) Multiply (ii) via 3 9x + 12y = -15 .....        (vii) Add vi to vii 17x = 17 ..........            (viii)  x = 1 Hence x = 1, y = -2  that is {1,-2} Posted by Damon | Posted Date: 2/12/2013 3:05:30 AM
