Question

solve by cross multiplication method x/a+y/b =2 and ax-by=a2-b2​ its ans is x=a and y =b help me for solution

Answer 1

Answer:

x = a, y = b

Step-by-step explanation:

Answer 2

Step-by-step explanation:

x/a+y/b=2

bx+ay=2ab - - (1)

ax-by=a^2-b^2 - - (2)

From (1)

bx=2ab-ay

x=(2ab-ay)/b

Substitue in (2)

a(2ab-ay)/b - by

a^2(2b-y)/b - by

(a^2(2b-y) - b^2y)/b

Compare with rhs

Coefficient of a ^2 is 1 and b ^2 is also 1

So (2b-y)/b =1 - - (3)

y/b =1 - - (4)

So y = b from*(4)

And Substitue this in (1)

bx + ab =2ab

bx = ab

So x = a
