To solve the first equation, we need to find the value of the question mark (?):

? - 5/14 = 3/7

First, we can add 5/14 to both sides of the equation:

? = 3/7 + 5/14
? = 6/14 + 5/14
? = 11/14

Therefore, the value of the question mark is 11/14.

To solve the second equation, we need to find the value of the question mark (?):

2/11 x ? = 4/5

First, we can multiply both sides of the equation by the reciprocal of 2/11, which is 11/2:

? = (4/5) x (11/2)
? = 44/10
? = 22/5

Therefore, the value of the question mark is 22/5.
