Answer 3

To solve the given system of equations:

2x + 11y = 15 ...(1) x - 11y = 9 ...(2)

We can use the method of substitution or elimination to find the values of x and y.

Let's solve it using the method of elimination:

Adding equation (1) and equation (2) eliminates the 'y' term:

(2x + 11y) + (x - 11y) = 15 + 9 3x = 24

Dividing both sides of the equation by 3, we get:

x = 8

Substituting the value of x into equation (2), we can find y:

8 - 11y = 9

Rearranging the equation:

-11y = 9 - 8 -11y = 1

Dividing both sides of the equation by -11:

y = -1/11

Therefore, the solution to the system of equations is: x = 8 y = -1/11
