Solve for x -3x+4=16

$- 3 x + 4 = 16$

Step 1

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

Subtract $4$ from both sides of the equation.

$- 3 x = 16 - 4$

Subtract $4$ from $16$ .

$- 3 x = 12$

Step 2

Divide each term in $- 3 x = 12$ by $- 3$ and simplify.

Divide each term in $- 3 x = 12$ by $- 3$ .

$\frac{- 3 x}{- 3} = \frac{12}{- 3}$

Simplify the left side.

Cancel the common factor of $- 3$ .

Cancel the common factor.

$\frac{- 3 x}{- 3} = \frac{12}{- 3}$

Divide $x$ by $1$ .

$x = \frac{12}{- 3}$

Simplify the right side.

Divide $12$ by $- 3$ .

$x = - 4$
