Question

2(x + 2) – 4x = 12 Solve for x in the equation below.

Answer 1

Hello :D

Answer:

X=-4

The answer should have a negative sign.

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 2

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
