In a rectangle, the diagonals are equal in length. In the case of rectangle ABCD, let the points A, B, C, and D be such that A is at one vertex, B is at an adjacent vertex, and O is the midpoint of diagonal AC.

The lengths AO and BO are given as:
- \( AO = 4x - 3 \)
- \( BO = 5x - 10 \)

Since O is the midpoint of the diagonals, we have the property that the lengths of AO and BO must be equal.

Setting the two expressions equal to each other, we have:

\[
4x - 3 = 5x - 10
\]

Now, we can solve for \( x \):

1. Rearrange the equation to isolate \( x \):
\[
4x - 5x = -10 + 3
\]
\[
-x = -7
\]

2. Multiply both sides by -1 to solve for \( x \):
\[
x = 7
\]

Thus, the value of \( x \) is \( \boxed{7} \).
