Find the Domain 7(x-y)=1470

Problem

7*(x−y)=1470

Solution

1. Identify the type of equation. The given equation 7*(x−y)=1470 is a linear equation in two variables, x and y

2. Solve for y to express it as a function of x Divide both sides by 7

x−y=210

3. Isolate the variable y to see the structure of the function.

y=x−210

4. Determine the restrictions on the input variable x Since y=x−210 is a polynomial (specifically a linear function), there are no values of x that result in division by zero or the square root of a negative number.

5. Conclude that the domain consists of all real numbers.

Final Answer

Domain: *(−∞,∞)
