Find the Domain n/2-(3n)/4+(5n)/6=21

Problem

n/2−(3*n)/4+(5*n)/6=21

Solution

1. Identify the type of equation. This is a linear equation in one variable, n

2. Examine the denominators of the terms. The denominators are the constants 2 4 and 6

3. Determine if there are any restrictions. Since there are no variables in any denominator and no square roots or logarithms, the expression is defined for all real numbers.

4. Conclude the domain. The variable n can take any value on the real number line.

Final Answer

Domain: *(−∞,∞)
