Q1NCERT Standard • 2 Marks2 Marks
Evaluate the exact mathematical value for Relations Functions when parameter x = 2 and y = 5 in standard board form.
▶ Show Detailed Solution
Step 1 (Parameters):
Given: x = 2, y = 5.
Step 2 (Substitution & Solution):
Apply standard theorem for Relations Functions: Result = (2)² + 3(5) = 4 + 15 = 19.
✔ Final Answer: 19
Q2CBSE Board 2024 • 3 Marks3 Marks
Solve the exact board examination equation for Relations Functions: 2x + 3y = 12 and 3x - y = 7.
▶ Show Detailed Solution
Step 1 (Elimination):
Multiply 2nd eq by 3: 9x - 3y = 21.
Add to 1st eq: 11x = 33 ⟹ x = 3.
Substitute: 3(3) - y = 7 ⟹ y = 2.
✔ Final Answer: x = 3, y = 2
