Access answers to Maths RD Sharma Solutions For Chapter 6 – Determinants Ex 6.4 Class 12 Important Questions With Solution
Solve the following system of linear equations by Cramer’s rule:
1. x – 2y = 4
-3x + 5y = -7
Solution:
Given x – 2y = 4
-3x + 5y = -7
Let there be a system of n simultaneous linear equations and with n unknown given by
Solving determinant, expanding along 1st row
⇒ D = 5(1) – (– 3) (– 2)
⇒ D = 5 – 6
⇒ D = – 1
Again,
Solving determinant, expanding along 1st row
⇒ D1 = 5(4) – (– 7) (– 2)
⇒ D1 = 20 – 14
⇒ D1 = 6
And
Solving determinant, expanding along 1st row
⇒ D2 = 1(– 7) – (– 3) (4)
⇒ D2 = – 7 + 12
⇒ D2 = 5
Thus by Cramer’s Rule, we have
2. 2x – y = 1
7x – 2y = -7
Solution:
