how much is an x block worth in the image below?

Explanation:

Step1: Set up an equation

Let the value of an (x) - block be (x). The left - hand side of the equation is (5x + 1), and the right - hand side is (-1-1 - 1-1=-4). So the equation is (5x+1=-4).

Step2: Subtract 1 from both sides

Subtract 1 from both sides of the equation (5x + 1=-4). We get (5x+1 - 1=-4 - 1), which simplifies to (5x=-5).

Step3: Solve for x

Divide both sides of the equation (5x=-5) by 5. So (x=\frac{-5}{5}=-1).

Answer:

(-1)
