Find the Domain 7x+8y=51.30

Problem

7*x+8*y=51.30

Solution

1. Identify the type of equation provided. This is a linear equation in two variables, x and y

2. Determine the constraints on the independent variable x In a linear equation of the form A*x+B*y=C there are no square roots, logarithms, or denominators containing x that would restrict its values.

3. Conclude that x can be any real number because the expression is defined for all real inputs.

4. Express the domain in interval notation or as a set of all real numbers.

Final Answer

Domain: *(−∞,∞)
