Multiply both sides by 9:

Expand brackets:

Add 32 to both sides:

Divide both sides by 8:

to be a parallelogram its front sides must be equal to each other
so, we equalize the length of two sides that are face to face

and solve for w

the value of w must be 10
18 8/16 = 18.5....rounded to the nearest whole number = 19
