It seems the original problem content (image) is not visible. However, I can provide a step-by-step solution to a common expression value problem as an example, which you can adapt to your actual problem:

Example Problem:

Given (5x + 3y = 17) and (3x + 5y = 19), find the value of (x + y).

Step 1: Add the two equations
((5x + 3y) + (3x + 5y) = 17 + 19)
Simplify left side: (8x + 8y = 36)

Step 2: Factor out the common term
(8(x + y) = 36)

Step 3: Solve for (x + y)
Divide both sides by 8:
(x + y = \frac{36}{8} = \frac{9}{2} = 4.5)

If your problem is different, please describe it in text (e.g., given equations, expression to find), and I’ll solve it for you!
Let me know the details.
