Solving Linear Equations Using Elimination Method Worksheet :
Worksheet given in this section will be much useful for the students who would like to practice problems on solving linear linear equations using elimination method.
(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
