Answer 2

To solve the equation, let's break down the different parts:

1. The expression (k - 5 целых 3/14) can be simplified as (k - 5 - 3/14).
2. The expression 8 целых 13/14 can be simplified as 8 + 13/14.

Now, let's substitute these values back into the equation:

(k - 5 - 3/14) + (8 + 13/14) = 3 целых 9/14

To add the fractions, we need a common denominator. The common denominator for 14 and 14 is 14.

(k - 5 - 3/14) + (8 + 13/14) = 3 целых 9/14

Combine like terms:

k - 5 - 3/14 + 8 + 13/14 = 3 целых 9/14

To simplify further, we can add the integers separately from the fractions:

(k + 8 - 5) + (-3/14 + 13/14) = 3 целых 9/14

(k + 3) + (10/14) = 3 целых 9/14

Simplify the fractions:

(k + 3) + (5/7) = 3 целых 9/14

To isolate the variable k, we can subtract 3 from both sides:

(k + 3) + (5/7) - 3 = 3 целых 9/14 - 3

(k + 5/7) = 3 целых 9/14 - 3

(k + 5/7) = 3 целых 9/14 - 3 целых 42/14

Simplify the mixed numbers:

(k + 5/7) = 3 целых 9/14 - 3 целых 3/14

(k + 5/7) = 3 целых (9 - 3)/14

(k + 5/7) = 3 целых 6/14

Reduce the fraction:

(k + 5/7) = 3 целых 3/7

Now, subtract 5/7 from both sides to isolate k:

k = 3 целых 3/7 - 5/7

k = 3 целых (3 - 5)/7

k = 3 целых (-2)/7

Since we have a negative numerator in the fraction, we can rewrite it as:

k = 3 целых -2/7

So, the solution is:

k = 3 целых -2/7
