Question

To draw the graph of 4x+5y=19, if x=1 is taken then what will be the value of y?​

Answer 1

Answer:

here is ur answer

Step-by-step explanation:

4x+5y=19

When x = 1, then y will be

4(1)+5y=19

⇒4+5y=19

⇒5y=19−4=15

⇒5y=15

⇒y=

5

15

=3

Hence, the correct answer is 3.

Answer 2

Given:

 4x + 5y = 19

  x = 1

To Find

 the value of y

Solution:

     x = 1 (given)

   ⇒ 4x + 5y = 19

   ⇒4(1) + 5y = 19

   ⇒4 + 5y = 19

   ⇒ 5y = 19 - 4

   ⇒ 5y = 15

   ⇒ y = 3

  So, y = 3

You can also check if the value is right by substituting the values of x and y with 1 and 3 respectively.

Therefore, the value of y is 3.
