$495.28 I think I'm not sure if I'm right.
Step-by-step explanation:

Subtract 5/8 on both sides
To subtract 5/8 we make the denominators same

Addition or Subtraction property of order is used

Subtract 4x on both sides
Addition or Subtraction property of order is used

Now divide both sides by -1
Multiplication or Division property of order is used

Set the height to h, and the width to w.
We know that wh=190 and h=2w-1.
Substituting 2w-1 for h, we have:
w(2w-1)=190
So:
2w^2-w-190=0
Factoring this equation, we get (2w+19)(w-10)=0. The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
