Question

by cramers rule 3x+y=1,2x=11y+3

Answer 1

Hiiii........

The given equations are :-

3x+y=1___(1)
2x=11y +3
therefore..2x-11y=3__(2)
Comparing the given equations with a1x+b1y =c1 and a2x +b2y =c2 respectively ..
we get:
a1=3,b1=1,c1=1
a2=2,b2=-11 ,c2=3

The answer is continued in the pic..
sorry for this but it was really difficult to type it..
Hope you understand.

Mark as brainliest if it helps...

Answer 2

Explanation:

b1 =1

DX= -11-3 = -14

[ DX= -14 ].

[Dy=7]

X= Dx÷D = -14÷(-35). { X= 2÷5 }

Y=Dy÷D=7÷(-35). { 1÷(-5)}
