Question

6x - 3y = -10 ; 3x + 5y - 8 = 0

please help me to solve this with cramer's rule​

Answer 1

here,

6x-3y=-10____1

3x+5y=8______2

Here,

a1=6. b1=-3 c1=_10

a2. 3 b2. =5 c2=8

By cramers rule

D= a1. b1

a2. b2

Dx=c1 b1

c2. b2

Dy= a1 c1

a2. c2

Here put the values of this and do cross multiplication.....

for ex

D= a1. b1 =a1*b2 -a2*b2

a2. b2.

Then you have to find the value of

$x$

Then to find the value of

$x$

$x = dx \div d$

similarly

$y = dy \div d$

then you be able to see your answer..

I hope it helps you

Thank you
