Introduction

In mathematics, solving for a variable is a fundamental concept that involves isolating the variable on one side of the equation. In this case, we are given an equation with a variable w and a constant -2.5. Our goal is to solve for w, which means finding the value of w that satisfies the equation. In this article, we will walk through the steps to solve for w in the given equation.

The Equation

The given equation is:

w−2.5=8\frac{w}{-2.5} = 8

Step 1: Multiply Both Sides by -2.5

To solve for w, we need to isolate w on one side of the equation. The first step is to multiply both sides of the equation by -2.5. This will eliminate the fraction and allow us to work with a simpler equation.

w=8×−2.5w = 8 \times -2.5

Step 2: Simplify the Right-Hand Side

Now that we have multiplied both sides by -2.5, we can simplify the right-hand side of the equation.

w=−20w = -20

Conclusion

In this article, we have solved for w in the given equation. By multiplying both sides of the equation by -2.5 and simplifying the right-hand side, we have found that w = -20. This means that the value of w that satisfies the equation is -20.
