To find the value of \( x \) in the parallelogram \( MNOP \) where the diagonals \( MO \) and \( NP \) intersect at point \( L \), we can use the properties of parallelograms.
In a parallelogram, the diagonals bisect each other, meaning that:
\[ ML = LO \]
From the information given:
- \( ML = x + 7 \)
- \( LO = 2x - 10 \)
Since \( ML = LO \), we can set the two expressions equal to each other:
\[ x + 7 = 2x - 10 \]
Now, let's solve for \( x \):
- Subtract \( x \) from both sides:
\[ 7 = x - 10 \]
- Add \( 10 \) to both sides:
\[ 7 + 10 = x \]
\[ x = 17 \]
Thus, the value of \( x \) is \( 17 \).
