Simplify 5/14a+−2/5c+1/8b−2/5c+3/8b+7/14a .

To simplify this expression, we can group like terms together.

First, let's group the terms with "a" together and the terms with "b" together.

The terms with "a" are 5/14a and 7/14a, which can be combined to give (5+7)/14a = 12/14a = 6/7a.

The terms with "b" are 1/8b and 3/8b, which can be combined to give (1+3)/8b = 4/8b = 1/2b.

Next, let's group the terms with "c" together. The terms are -2/5c and -2/5c, which can be combined to give (-2-2)/5x = -4/5c.

Now we have simplified the expression to 6/7a + 1/2b - 4/5c.
