Question

identify the equation- 8x² +7xy​

Answer 1

Answer:

and B = [□8(6&8@7&9)] verify that (AB)-1 = B-1 A-1 Taking L.H.S (AB)–1 First calculating AB AB = [□8(3&7@2&5)] [□8(6&8@7&9)] = [□8(3(6)+7(7)&3(8)+7(9)@2(6)+5(7)&2(8)+5(9))] ...

Answer 2

Answer:

$\bold\red{ † Answer † }$

4x + y = 3xy ---------(1)

8x + 3y = 7xy ----------(2)

Multiplying (1) by 2

It gets 8x + 2y = 6y ----------(3)

Solving (2) and (3)

y = xy

=> x = 1

From (1) , y = 2
