Question

solve the following pair of linear equation by cross multiplication method 8x+5y=9
3x +2y=4 anyone plzzz give me the correct ans of this question
​

Answer 1

Step-by-step explanation:

Given, pair of equations is 8x+5y−9=0 and 3x+2y−4=0

By cross-multiplication method, we have

⇒

−20+18

x

=

−27+32

y

=

16−15

1

⇒

−2

x

=

5

y

=

1

1

I II III

On taking I and III ratio, we get

⇒

−2

x

=

1

1

⇒x=−2

On taking II and III ratio, we get

⇒

5

y

=

1
