Question

9 X + 5 Y is equal to 37 x y, 7 x minus 4 Y is equal to 13 x y

Answer 1

Answer:

9x+5y=37xy

7x-4y=13xy

by elimination method it can be done

9x+5y=37xy*7

7x-4y=13xy*9

evaluate the equation :-

63x+35y=259xy

63x-36y=117xy

change the sign of lower number

then the first number along with the variable will be cancelled

left :-

71y=142xy

y and y will be cancelled

71=142x

therefore

x=71/142=1/2

hence

put the value of X in of the equation

answer will come
