Answer:

Qno, 1


Step-by-step explanation:

4x+3y=18

3x+2y=5


Multiply 1 St equation into 2

Multiply 2 ND equation into 3


Then you get

8x+6y=36

9x+6y=15


-x=21


X=-21

Substitute x value in 1

4(-21)+3y=18

-84+3y=18

3y= 18+84

3y=92

Y=3.6


kalpana26: wrong ans
kalpana26: u had mistake
