SOLVING LINEAR EQUATIONS USING ELIMINATION METHOD WORKSHEET

(1)  Solve by the method of elimination

(i) 2x – y = 3; 3x + y = 7            Solution

(ii) x – y = 5; 3x + 2y = 25               Solution

(iii)  (x/10) + (y/5)  =  14 ; (x/8) + (y/6)  =  15     Solution

(iv) 3(2x + y) = 7xy; 3(x + 3y) = 11xy        Solution

(v)  (4/x) + 5y  =  7, (3/x) + 4y  =  5        Solution

(vi) 13x + 11y = 70; 11x + 13y = 74    Solution
