Find the Domain x-17=21

Problem

x−17=21

Solution

1. Identify the type of expression or equation provided. The equation x−17=21 is a linear equation involving a single variable x

2. Determine if there are any restrictions on the variable. Restrictions typically occur with denominators (which cannot be zero), square roots of negative numbers, or logarithms of non-positive numbers.

3. Analyze the operations present. The equation involves only subtraction and equality, which are defined for all real numbers.

4. Conclude the domain. Since there are no values of x that would make the expression undefined, the domain consists of all real numbers.

Final Answer

Domain:(−∞,∞)
