The figure appears to be a parallelogram with diagonals AC and BD with E as the point of intersection of the two diagonals and also the midpoint.

Diagonal AC has segments AE measuring 3x + 1 and EC measuring x + 25. Since point E is the midpoint of the mentioned diagonal, therefore, we can say that the segments AE and EC should be congruent.

We get,


\text{ AE = EC}

Let's use this relationship to find x.


\text{ AE = EC}
\text{ 3x + 1 = x + 25}
\text{ 3x + 1 - x - 1 = x + 25 - x - 1}
\text{ 2x = 24}
\text{ }\frac{\text{2x}}{2}\text{ = }\frac{\text{24}}{2}
\text{ x = 12}

Therefore, x = 12.
