Answer:

x = − 3

Step-by-step explanation:

Let's solve your equation step-by-step.

− 2x − 4 = x + 5

Step 1: Subtract x from both sides.

− 2x − 4 − x = x + 5 − x

− 3x − 4 = 5

Step 2: Add 4 to both sides.

− 3x − 4 + 4 = 5 + 4

−3x = 9

Step 3: Divide both sides by -3.

−3x  / −3  =  9  / −3

x = − 3
