$x - 4 - 3 x = - 2 x - 3 - 1$

Step 1

Subtract $3 x$ from $x$ .

$- 2 x - 4 = - 2 x - 3 - 1$

Step 2

Subtract $1$ from $- 3$ .

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

Step 3

Move all terms containing $x$ to the left side of the equation.

Step 3.2.1

Add $- 2 x$ and $2 x$ .

$0 - 4 = - 4$

Step 3.2.2

Subtract $4$ from $0$ .

$- 4 = - 4$

Step 4

Since $- 4 = - 4$ , the equation will always be true for any value of $x$ .
