In a rectangle, the diagonals bisect each other at their midpoint. Therefore, the lengths of the segments from the vertices to the intersection point (O) of the diagonals must be equal.
In this case, we have the lengths:
- \( AO = 4x - 3 \)
- \( BO = 5x - 10 \)
Since \( AO \) and \( BO \) are equal, we can set up the following equation:
\[ 4x - 3 = 5x - 10 \]
To solve for \( x \), first, rearrange the equation:
- Subtract \( 4x \) from both sides:
\[ -3 = x - 10 \]
- Next, add 10 to both sides:
\[ 7 = x \]
So, the value of \( x \) is \( 7 \).
Thus, the answer is:
\( x = 7 \)
