Question

(1) To draw graph of 4x + 5y = 19, Find y when x = 1.
(A) 4
(B) 3
(C) 2
(D) -3
​

Answer 1

Answer:

4x-5y =19

x=1

5y =19-4

5y =15

y=3

Answer 2

Answer:

B) 3

Step by step solution

4x + 5y = 19

Put x=1 in above equation the we get,

4*1 + 5y = 19

5y = 19 - 4

5y = 15

y = 15/5

y = 3
