Question

x/a+y/b =a+b, x/a²+y/b²=2. solve for x and y by substitution method.​

Answer 1

Step-by-step explanation:

x/a + y/b = a+b 

⇒y/b = a + b - x/a     .................. i 

x/a² + y/b² = 2 ................ii

⇒x/a² + y/b x1/b = 2

⇒x/a² + a+b/b - x/ab = 2                 puttting i 

⇒x(b-a)/a²b = (b-a)/b

⇒x = a²

so x = a² 

using ii we get 

y = b²

so x=a² and y=b² ANSWER
