3. 11x-7y=-14. X-2y=-4

The two given equations are

11x - 7y = - 14

x - 2y = - 4

Now let us take the second equation for finding the value of x first

x - 2y = - 4

x = 2y - 4

Now we have to put the value of x in the first equation

11x - 7y = - 14

11 (2y - 4) - 7y = - 14

22y - 44 - 7y = - 14

15y = 44 - 14

15y = 30

y = 30/15

= 2

Now let us put the value of y in the second equation

x - 2y = - 4

x - 2 (2) = - 4

x - 4 = - 4

x = - 4 + 4

= 0

So the value of x is 0 and the value of y is 2.
