Question

5 5. If x varies directly with 3y + 5 and y= 3 when x = 10, then what is the value of y when x = 36?​

Answer 1

Answer:

x Varies directly with 3y+5

i.e., x=K(3y+5)

If y=

5

3

when x=10

⟹10=K(3×

5

3

+5)

⟹10=K(

5

9

+5)

⟹10=K×

5

34

⟹K=10×

34

5

=

17

25

∴x=

17

25

(3y+5)

When x=35 then,

35=

17

25

(3y+5)

⟹35×

25

17

=3y+5

⟹

5

119

=3y+5

⟹

5

119

−5=3y

⟹

5

94

=3y

∴y=

15

94
