Question

x/a =y/b
ax + by = a² + b^2
solve by substitution or elimination or cross multiplication method. plz explain stepwise.​

Answer 1

Step-by-step explanation:

x/a=y/b.

so X=ay/b

putting the value of X in eq.

ax +by=a2+b2

a.ay/b+by=a2+b2

a2y+b2y/b=a2+b2

y(a2+b2)=b(a2+b2)

y=b

now putting the value of y in eq.

X= ay/b

so X=a and y=b
