Answer:
================================================
Work Shown:
Part 1
Part 2
-------------------------------
Explanations:
- There are quite a bit of steps. I decided to break things into two parts.
- The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.
- Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.
- From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).
- The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero.
- If the formulas don't properly display, then you might have to refresh the page.
The correct algebraic expression is X ÷ 5 - 17 = 41
<h3>What is an algebraic expression?</h3>An algebraic expression is a term that refers to a way of representing mathematical operations in which letters and numbers are combined, related to signs of the operations such as:
- Addition (+)
- Subtraction (-)
- Multiplication (×)
- Division (÷)
- Empowerment (
)
According to the above, we can infer that the correct algebraic expression would be:
- X ÷ 5 - 17 = 41
In this algebraic expression the letter X represents a number that we do not know and we must find.
