Question

solve by Cramer's rule 3x-2y=3;2x+y=6​

Answer 1

GIVEN EQUATIONS=


comparing with a1x +biy=c1 and a2x+b2y=c2
we get

D=a1×b2-a2×b1
=3×1-2×-2
=3-(-4)
=3+4
=7

Dx=c1×b2-c2×b1
=3×1-6×-2
=3-(-12)
=3+12
=15

Dy=a1×c2-a2×c1
=3×6-2×3
=18-6
=12

♧♧BY CRAMER'S RULE

X=Dx/D
=15/7


Y=Dy/D
=12/7



SO THE SOLUTION IS X,Y=15/7,12/7
