$2 x = y + 8$

Step 1

Rewrite the equation as $y + 8 = 2 x$ .

$y + 8 = 2 x$

Step 2

Subtract $8$ from both sides of the equation.

$y = 2 x - 8$

Step 3

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
