Question

the solution of the equation 5x -9 = 1/y & x + 1/y = 3​

Answer 1

Step-by-step explanation:

Let 1/y=p

5x-9=p or X+p=3

5x-9-p=0 (1)

x+p-3=0 (2)

from (1)

5x-p=9

5x=9+p

X=9+p/5

put the X value in equation 2

x+p-3=0

(9+p/5)+p-3=0

(9+p/5)-(p/1)+(3/1)=0

9+p+5p-15/5=0

9+p+5p-15

6p-6=0

6p=6

p=1

put the value of p in equation 1

5x-9-p=0

5x-9-1=0

5x-10=0

5x=10

x=10/5

x=2. answer (X)

y=1
