Answer:
To solve this equation, you need to first subtract x from both sides of the equation to get: y = 11 - x. Then, substitute this value into the second equation to get: 2x + (11 - x) = 19. Simplifying this equation gives: 3x = 8. Dividing both sides of the equation by 3 gives: x = 8/3. Finally, substituting this value for x in the first equation gives: y = 11 - (8/3) = 11 - 2.5 = 8.5. Therefore, x = 8/3 and y = 8.5.
