Question

solve the simultaneous linear equation 5x-9=1/y and x+1/y=3​

Answer 1

Answer:

x=2y=1

Step-by-step explanation:

we have 1/y=5x-9

substitute the value in second equation

x+5x-9=3

6x-9=3

6x=12

x=2

now we have the value of x we put the value of x in first equation

5x-9=1/y

(5*2)-9=1/y

10-9=1/y

1=1*y

y=1

Answer 2

Answer:

vese ye mere 2nd id hai

Step-by-step explanation:

apka answer

5x−9=

y

1

⇒ 5xy−9y=1 ----- ( 1 )

x+

y

1

=3

⇒ xy+1=3y

⇒ xy−3y=−1

Multiplying both sides by 3, we get

⇒ 3xy−9y=−3 ----- ( 2 )

Subtracting eqation ( 2 ) by ( 1 ) we get,

2xy=4

∴ xy=2

Substituing xy=2 in equation ( 1 ) we get,

⇒ 5(2)−9y=1

⇒ 10−9y=1

⇒ 9y=9

∴ y=1

Now, substituting value of y in ( 1 ) we get,

⇒ 5x(1)−9(1)=1

⇒ 5x−9=1

∴ 5x=10

∴ x=2

⇒ (x,y)=(2,1)
