To solve this equation, we first need to combine the whole numbers and fractions on each side.

12 21/29 + x + 4 23/29 = 12 2/29
(12 + 4) + (21/29 + 23/29) + x = 12 + 2/29
16 + 44/29 + x = 12 + 2/29

Next, simplify the fractions by finding a common denominator:

16 + 44/29 + x = 12 + 2/29
16 + (44 + 29x)/29 = (12 * 29 + 2)/29
16 + (44 + 29x)/29 = 350/29

Now, we can isolate x by subtracting 16 from both sides and then multiplying both sides by 29 to eliminate the fraction:

(44 + 29x)/29 = 350/29 - 16
44 + 29x = 350 - 464
29x = -114
x = -114/29

Therefore, the solution to the equation is x = -114/29.
