Here we are going to see some practice problems on solving linear equations using elimination method.
Solving Linear Equations Using Elimination Method Worksheet - Practice questions
(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
(2) The monthly income of A and B are in the ratio 3:4 and their monthly expenditures are in the ratio 5:7. If each saves ₹ 5,000 per month, find the monthly income of each. Solution
(3) Five years ago, a man was seven times as old as his son, while five year hence, the man will be four times as old as his son. Find their present age.Five years ago, a man was seven times as old as his son, while five year hence, the man will be four times as old as his son. Find their present age. Solution
