Write as a Function of x 4x^2-3y=-x+2y

$4 x^{2} - 3 y = - x + 2 y$

Step 1

Move all terms containing $y$ to the left side of the equation.

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

$4 x^{2} - 3 y - 2 y = - x$

Subtract $2 y$ from $- 3 y$ .

$4 x^{2} - 5 y = - x$

Step 2

Subtract $4 x^{2}$ from both sides of the equation.

$- 5 y = - x - 4 x^{2}$

Step 3

Divide each term in $- 5 y = - x - 4 x^{2}$ by $- 5$ and simplify.

Divide each term in $- 5 y = - x - 4 x^{2}$ by $- 5$ .

$\frac{- 5 y}{- 5} = \frac{- x}{- 5} + \frac{- 4 x^{2}}{- 5}$

Simplify the left side.

Cancel the common factor of $- 5$ .

Cancel the common factor.

$\frac{- 5 y}{- 5} = \frac{- x}{- 5} + \frac{- 4 x^{2}}{- 5}$

Divide $y$ by $1$ .

$y = \frac{- x}{- 5} + \frac{- 4 x^{2}}{- 5}$

Simplify the right side.

Simplify each term.

Dividing two negative values results in a positive value.

$y = \frac{x}{5} + \frac{- 4 x^{2}}{- 5}$

Dividing two negative values results in a positive value.

$y = \frac{x}{5} + \frac{4 x^{2}}{5}$

Step 4

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.

$f (x) = \frac{x}{5} + \frac{4 x^{2}}{5}$

Write as a Function of x 4x^2-3y=-x+2y
