Answer:

5x+2y=36-------(1)

2x+3y=43-------(2)

Now ,

from(1)

5x+2y=36

or, X=(36-2y)/5-------------------(3)

now putting the value of x in eqn ----(2)

72-4y+3y=43

or, 72-43=y

:- Y=29✔️✔️

Again .putting the value of Y in eqn-----(3) we get,

;- X=(36-2×29)/5

or, X=(36-58)/5

or, X=. (-22)/5

X= (-22)/5 or 4.4✔️✔️
