Solve for x kx+7=4 for x

$k x + 7 = 4$ for $x$

Move all terms not containing $x$ to the right side of the equation.

Subtract $7$ from both sides of the equation.

$k x = 4 - 7$

Subtract $7$ from $4$ .

$k x = - 3$

Divide each term in $k x = - 3$ by $k$ and simplify.

Divide each term in $k x = - 3$ by $k$ .

$\frac{k x}{k} = \frac{- 3}{k}$

Simplify the left side.

Cancel the common factor of $k$ .

Cancel the common factor.

$\frac{k x}{k} = \frac{- 3}{k}$
