Question

Q1. Solve
the following :
draw the graph of 3x+4y = 19, find the value of y, when x=1
​

Answer 1

Answer:

y=4

Step-by-step explanation:

As 3 multiplied by 1 becomes 3 ,when moved to RHS becomes 19-3

Accordingly y=4

Answer 2

-Step-by-step explanation:given is that x=1

therefore put x=1 in equation

therefore 3*1+4y=19

4y=19-3

4y=16

y=4
