Find the Domain 0.5x-0.7y=1.5

Problem

0.5*x−0.7*y=1.5

Solution

1. Identify the type of equation. 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 of negative numbers, no denominators that could be zero, and no logarithms.

3. Conclude that the variable x can take any real number value.

4. Express the domain in interval notation. Since there are no restrictions, the domain is all real numbers.

Final Answer

Domain: *(−∞,∞)
