One number is 6 more than twice another. If their sum is 51, find the numbers. Which of the following systems of equations represents the word problem?
Ay = 2x + 6 and y = x + 51
B= 2x + 6 and x + y = 51
Cy = 2(x + 6) and x + y = 51
Ay = 2x + 6 and y = x + 51
B= 2x + 6 and x + y = 51
Cy = 2(x + 6) and x + y = 51
