Question

urgently need help please​

Answer 1

Step-by-step explanation:

ax+by=1 (1)

bx+ay=(a+b) ²÷(a²+b²)-1 (2)

multiple with y in (1)

and multiple with x in (2)

axy+by²=y

axy+bx²=(a+b) ²x÷(a²+b²) -x

___________________

b(x²-y²)=(y-x) -(a+b) ²x÷(a²+b²)

b= (y+x) -(a+b) ²x÷(a²+b²)(x²-y²)

now multiple with x in (1) and y in (2)

calculate and get a

hope u understand

mark as brilliant
