Question

(3) Find the values of Dx and D for the equations.
2 + 3y = 4; 7x - 5y = 2
2​

Answer 1

Answer:

Dx=-26 and D=-31

Step-by-step explanation:

The given equations are 2x+3y=4 and 7x-5y=2, using the crammer's rule,

D=determinant

D=-10-21

D=-31

And, Dx= determinant

Dx= -20-6=-26.

Hence, Dx=-26 and D=-31
