Question

What is the value of D, for solving simultaneous equations x + y = 3 ; 3x - 2y - 4 = 0 by determinant method?*

2 किंवा -2 / 2 or -2

3 किंवा -3 / 3 or -3

5 किंवा -5 / 5 or -5

1 किंवा -1/ 1 or -1

​

Answer 1

Answer:

In Cramer's method, the equations are written as a1x + b1y = c1 & a2x + b2y = c2. Write the equations as a1x + b1y = c1 & a2x + b2y = c2. Hence , the value of D is - 5.
