solve for X and Y using substitution method 2x + 5y/xy = 6 and 4x - 5y /xy = -3 where x and y are not equal to zero​

Answer»

Answer:

2x + 5y = 6xy \\ 4x - 5y =  - 3xy \\   on \: solving \: these \\ 6x = 3xy \\ y = 2 \\ put \: value \: of \: y \: in \: above \: eq \\ weget \:  \\ 2x + 10 = 12x \\ 10 = 10x \\ <klux>1</klux> = <klux>X</klux> \\

so the valuesof x and y are 1 and 2 respectively
