Determine if Linear 12x+5xy=11y

$12 x + 5 x y = 11 y$

Step 1

Solve the equation for $y$ .

Subtract $11 y$ from both sides of the equation.

$12 x + 5 x y - 11 y = 0$

Subtract $12 x$ from both sides of the equation.

$5 x y - 11 y = - 12 x$

Factor $y$ out of $5 x y - 11 y$ .

Factor $y$ out of $5 x y$ .

$y (5 x) - 11 y = - 12 x$

Factor $y$ out of $- 11 y$ .

$y (5 x) + y \cdot - 11 = - 12 x$

Factor $y$ out of $y (5 x) + y \cdot - 11$ .

$y (5 x - 11) = - 12 x$

Divide each term in $y (5 x - 11) = - 12 x$ by $5 x - 11$ and simplify.

Divide each term in $y (5 x - 11) = - 12 x$ by $5 x - 11$ .

$\frac{y (5 x - 11)}{5 x - 11} = \frac{- 12 x}{5 x - 11}$

Simplify the left side.

Cancel the common factor of $5 x - 11$ .

Cancel the common factor.

$\frac{y (5 x - 11)}{5 x - 11} = \frac{- 12 x}{5 x - 11}$

Divide $y$ by $1$ .

$y = \frac{- 12 x}{5 x - 11}$

Simplify the right side.

Move the negative in front of the fraction.

$y = - \frac{12 x}{5 x - 11}$

Step 2

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be $0$ or $1$ for each of its variables. In this case, the degree of variable $y$ is $1$ , the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

Not Linear
