Find the Domain 9x=2x+y

Problem

9*x=2*x+y

Solution

1. Isolate the variable y to express it as a function of x

y=9*x−2*x

2. Simplify the expression by combining like terms.

y=7*x

3. Identify the type of function. The equation y=7*x is a linear function.

4. Determine the constraints on the input variable x Since there are no denominators, square roots of negative numbers, or logarithms, x can be any real number.

Final Answer

Domain: *(−∞,∞)
