Linear Equations
9 lessons · 18 questions · 2 PYQs
What the exams ask here
- word problem -> 2 equations
- k for infinitely many solutions
- Celsius/Fahrenheit misuse
- shopping problems
- 2x + 3y = 7 and 2px + (p - q)y = 28 with infinitely many solutions -> (p, q) (JIPMAT 2023 Q3)
- F = 1.8C + 32: x degrees F reported as x degrees C is 144% higher -> 122 (Indore 2026 SA, memory-based)
- 23x + 47y = 140, 47x + 23y = 140 -> x + y
- two equations in three unknowns -> a fixed combination (2x + 3y - z = 10, x - y + 2z = 5 -> 7x + 3y + 4z)
- digits and fractions
