$1 y - 2 x = - 3$

Step 1

Multiply $y$ by $1$ .

$y - 2 x = - 3$

Step 2

Add $2 x$ to both sides of the equation.

$y = - 3 + 2 x$

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.
