Final answer:

The most appropriate first step to take when solving the equation √7x-2x-x=4 is to subtract x from both sides.

The answer is option ⇒b

Step-by-step explanation:

Here's a step-by-step explanation:

  • 1. The equation is √7x - 2x - x = 4.
  • 2. We have two terms with x: -2x and -x. We can combine them to get -3x.
  • 3. The equation now becomes √7x - 3x = 4.
  • 4. To simplify further, we can subtract x from both sides.
  • 5. Subtracting x from both sides gives us √7x - 3x - x = 4 - x.
  • 6. Simplifying the equation further, we get √7x - 4x = 4 - x.

Now, we can continue solving the equation by isolating the square root term and simplifying further. However, subtracting x from both sides is the most appropriate first step in this case (Option B).

The answer is option ⇒B
