Simplify the left side.

Tap for more steps...

Simplify each term.

Tap for more steps...

Apply the distributive property.

$3 x + (- 4 x - 4 \cdot 4) = 2$

Multiply $- 4$ by $4$ .

$3 x + (- 4 x - 16) = 2$

$3 x + (- 4 x - 16) = 2$

Simplify by adding terms.

Tap for more steps...

Remove unnecessary parentheses.

$3 x - 4 x - 16 = 2$

Subtract $4 x$ from $3 x$ .

$- x - 16 = 2$

$- x - 16 = 2$

$- x - 16 = 2$

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

Tap for more steps...

Add $16$ to both sides of the equation.

$- x = 16 + 2$

Add $16$ and $2$ .

$- x = 18$

$- x = 18$

Multiply each term in $x = - 18$ by $- 1$

Tap for more steps...

Multiply each term in $- x = 18$ by $- 1$ .

$- x \cdot - 1 = 18 \cdot - 1$

Simplify $- x \cdot - 1$ .

Tap for more steps...

Multiply $- 1$ by $- 1$ .

$1 x = 18 \cdot - 1$

Multiply $x$ by $1$ .

$x = 18 \cdot - 1$

$x = 18 \cdot - 1$

Multiply $18$ by $- 1$ .

$x = - 18$

$x = - 18$
