Question

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

value of y?

A) 4 B) 3 C) 2 D) −3​

Answer 1

Answer:

b) 3

Step-by-step explanation:

4x + 5y = 19

Here, x = 1

So, 4 + 5y = 19

5y = 19-4

5y = 15

y = 15/5

y = 3

Answer 2

Answer:

b)3

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=$\frac{15}{5}$

     =3

Hence, the correct answer is 3.
