Find Dx and Dy of the given simultaneous equations. 3x - 2y = 3 and 2x + y = 16

iii. Find Dx and Dy  of the given simultaneous equations. 3x  - 2y = 3   and 2x + y = 16

Answer. The given equations are 3x  - 2y = 3   and 2x + y = 16

D =


=
(3× 1) – (2 × - 2)
=
3 + 4
=

Dx =


=
(3× 1) – [16× (-2)]
=
3 + 32
=
