Solve for y xy+7=n

$x y + 7 = n$

Subtract $7$ from both sides of the equation.

$x y = n - 7$

Divide each term in $x y = n - 7$ by $x$ and simplify.

Divide each term in $x y = n - 7$ by $x$ .

$\frac{x y}{x} = \frac{n}{x} + \frac{- 7}{x}$

Simplify the left side.

Cancel the common factor of $x$ .

Cancel the common factor.

$\frac{x y}{x} = \frac{n}{x} + \frac{- 7}{x}$

Divide $y$ by $1$ .

$y = \frac{n}{x} + \frac{- 7}{x}$

Simplify the right side.

Move the negative in front of the fraction.

$y = \frac{n}{x} - \frac{7}{x}$
