Hello :D

Answer:

<u><em>X=-4</em></u>

<u><em>The answer should have a negative sign.</em></u>

Step-by-step explanation:

Distributive property

   ↓

A(B+C)=AB+AC

Expand the form.

2(x-2)-4x=-2x+4

-2x+4=12

Then, you subtract by 4 both sides of an equation.

-2x+4-4=12-4

Subtract the numbers from left to right.

12-4=8

-2x=8

Divide by -2 both sides of an equation.

\frac{-2x}{-2}=\frac{8}{-2}

Finally, you divide by the numbers from left to right to find the answer.

8\div-2=-4

X=-4 is the correct answer.

Hope this helps you!

Have a wonderful day! :D

Answer:

x = -4

Step-by-step explanation:

Distribute 2 inside the parentheses

2\times x = 2x\\ 2\times2=4\\ 2x+4 - 4

Combine like terms

-4x + 2x = -2x + 4 = 12

Subtract 4 from both sides

-2x = 8

x = -4
