Question

$$\left. \begin{array} { l } { - 3 x - ( 4 - 2 x ) = x - 4 } \end{array} \right.$$

Solve for x

$x=0$

Steps for Solving Linear Equation

To find the opposite of $4-2x$, find the opposite of each term.

$$-3x-4-\left(-2x\right)=x-4$$

The opposite of $-2x$ is $2x$.

$$-3x-4+2x=x-4$$

Combine $-3x$ and $2x$ to get $-x$.

$$-x-4=x-4$$

Subtract $x$ from both sides.

$$-x-4-x=-4$$

Combine $-x$ and $-x$ to get $-2x$.

$$-2x-4=-4$$

Add $4$ to both sides.

$$-2x=-4+4$$

Add $-4$ and $4$ to get $0$.

$$-2x=0$$

Product of two numbers is equal to $0$ if at least one of them is $0$. Since $-2$ is not equal to $0$, $x$ must be equal to $0$.

$$x=0$$
