by substitution method
2(3x-y) =5xy
2(x + 3y) = 7xy​

Answer 1

ok

i have done bro / sis okkkk

Answer 2

..............1............

$2(3x - y) = 5xy$

$(6x - 2y) = 5xy$

$4xy = 5xy$

$xy - xy = 5 + 4$

${x}^{2} {y}^{2} = 9$

..............2.............

$2(x + 3y )= 7xy$

$(2x + 6y) = 7xy$

$8xy = 7xy$

$xy - xy = 7 + 8$

${x}^{2} {y}^{2} = 15$
