Question

could you please help me with this question​

Answer 1

Step-by-step explanation:

Given x+y=8

x+1=(15x+y/15y)(y+1)

or x=8-y

put it in eqn

we got, 8-y=15(8-y)/15y(y+1)

or 8-y=120-15y/15y(y+1)= 8/y-1(y+1)

= 8-y(y-1)=8y+8(cross multiplication)

8y-8-y'2+1=8y+8

y'2=-15

$y = \sqrt{ - 15}$
