Step 1 :The problem is asking for the value of x. Since LT and BY are sides of a rectangle, they are equal. Therefore, we can set the two expressions equal to each other and solve for x.
Step 2 :Setting the two expressions equal to each other gives us the equation \(4x - 5 = 7x - 8\).
Step 3 :Solving this equation gives us the final answer: \(x = \boxed{1}\).
