What Does the Expression 8x - -7 Mean?
The expression "8x - -7" can initially seem daunting, especially with the presence of two negative signs. However, understanding the fundamentals of algebra can simplify it significantly. The first step involves recognizing that subtracting a negative number is equivalent to adding a positive one. Therefore, the expression can be rewritten as "8x + 7". This transformation is crucial as it sets the stage for further calculations.
How Do We Simplify 8x - -7?
Simplifying "8x - -7" to "8x + 7" is straightforward. Here’s how to do it step by step:
- Identify the negative sign before the second term (-7).
- Recognize that subtracting a negative is equivalent to adding a positive.
- Rewrite the expression as "8x + 7".
Can You Solve for x in 8x - -7?
Now that we have simplified the expression to "8x + 7", we can solve for x by setting the expression equal to a value. For example, if we set it equal to 0:
