Let's solve the equation step by step:
-4(5-2x) = 8
First, distribute -4 across the parentheses:
-20 + 8x = 8
Next, isolate the x-term by subtracting -20 from both sides:
8x = 28
To solve for x, divide both sides by 8:
x = 28/8
Simplifying the right side:
x = 3.5
Therefore, the solution to the equation is x = 3.5.
The correct answer is A. 3.5.
