Answer 3

To solve the equation, let's follow the order of operations:

1. Start by evaluating the expression within the parentheses: (x • 0.25) • 4

2. Perform the multiplication inside the first parentheses: 0.25 * x = 0.25x

3. Now, we have: (0.25x) • 4

4. Perform the final multiplication: 0.25x * 4 = 1x = x

So, the equation simplifies to: x = 2.1

Therefore, the solution to the equation is x = 2.1.
