Question

1. x+ y - 10. 2x + 1. y. = 11
3. 3; 4 4​

Answer 1

Answer:

x=1;y=9. i hope it is help for you

Answer 2

Answer:

Solution:

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



Clearly two lines intersect at a point P (1, 2)

Hence x = 1 and y = 2
