Question

W. To draw the graph of 4x+5y=19, if x=1 then y = ?
a) 4
b)3
c) 2
d) -3​

Answer 1

Answer:

To draw the graph of 4x+5y=19, if x=1 then y=3.

Step-by-step explanation:

If x=1 ,

4x+5y=19

4(1)+5y=19

4+5y=19

5y=19-4

5y=15

y=15/5

y=3

Verification;

x=1 , y=3

x=1 , y=3LHS=4(1)+5(3)

x=1 , y=3LHS=4(1)+5(3)=4+15

x=1 , y=3LHS=4(1)+5(3)=4+15=19 =RHS

x=1 , y=3LHS=4(1)+5(3)=4+15=19 =RHSLHS=RHS
