The figure is a rectangle for x=10

Step-by-step explanation:

we know that

If the figure MLON is a rectangle (see the attached figure to better understand the problem)

then

The diagonals must be congruent

so      

LN=MO

substitute the given values and solve for x

4x-7=2x+13

Group terms

4x-2x=13+7

2x=20

x=10
