Write as a Function of x 2x-4y=-4

$2 x - 4 y = - 4$

Step 1

Subtract $2 x$ from both sides of the equation.

$- 4 y = - 4 - 2 x$

Step 2

Divide each term in $- 4 y = - 4 - 2 x$ by $- 4$ and simplify.

Divide each term in $- 4 y = - 4 - 2 x$ by $- 4$ .

$\frac{- 4 y}{- 4} = \frac{- 4}{- 4} + \frac{- 2 x}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 y}{- 4} = \frac{- 4}{- 4} + \frac{- 2 x}{- 4}$

Divide $y$ by $1$ .

$y = \frac{- 4}{- 4} + \frac{- 2 x}{- 4}$

Simplify the right side.

Simplify each term.

Divide $- 4$ by $- 4$ .

$y = 1 + \frac{- 2 x}{- 4}$

Cancel the common factor of $- 2$ and $- 4$ .

Factor $- 2$ out of $- 2 x$ .

$y = 1 + \frac{- 2 (x)}{- 4}$

Cancel the common factors.

Factor $- 2$ out of $- 4$ .

$y = 1 + \frac{- 2 (x)}{- 2 (2)}$

Cancel the common factor.

$y = 1 + \frac{- 2 x}{- 2 \cdot 2}$

Rewrite the expression.

$y = 1 + \frac{x}{2}$

Step 3

To rewrite as a function of $x$ , write the equation so that $y$ is by itself on one side of the equal sign and an expression involving only $x$ is on the other side.

$f (x) = 1 + \frac{x}{2}$

Write as a Function of x 2x-4y=-4
