Here, a₁/a₂ = 5/7 and b₁/b₂ = -4/6 = -2/3. Since a₁/a₂ ≠ b₁/b₂, the system possesses a unique solution, meaning the lines intersect at a single point. Class 9 Maths (Ganita Manjari part two) Chapter 13 questions answer Class 9 ...
Let boys be x and girls y. The equations are x + y = 10 and y – x = 4. Graphing both lines reveals their unique intersection point at (3, 7). Thus, 3 boys and 7 girls participated. Ganita Manjari ...
Let fixed charge be ₹x and daily extra charge ₹y. Saritha kept it 7 days: x + 4y = 27. Susy kept it 5 days: x + 2y = 21. Subtracting gives 2y = 6, so y = 3 and ...
Let x be ₹50 notes and y be ₹100 notes. Then x + y = 25 and 50x + 100y = 2000 or x + 2y = 40. Subtracting gives y = 10, so x = 15. Meena received 15 ...
