Question

x+y=4 and 2x-3y=-18 by graphical method
​

Answer 1

Step-by-step explanation:

2x + 5y = 12

We have,

x + y = 3

When y = 0 we have x = 3

When x = 0 we have y = 3

Thus we have the following table giving points on the line x + y = 3

X03Y30

Now, 2 + 5y = 12

When x = 1, we have

Thus we have the following table giving points on the line 2x + 5y = 12

X1-4Y24

 Graph of the equation x + y = 3 and 2x + 5y = 12 is given
