Question

What is the value of x in the equation 2(x-4) = 4(2x + 1)?

Answer 1

Answer:

$x = - 2$

Step-by-step explanation:

$2(x - 4) = 4(2x + 1) \\ 2x - 8 = 8x + 4 \\ 2x - 8x = 8 + 4 \\ - 6x = 12 \\ \frac{ - 6x}{ - 6} = \frac{12}{ - 6} \\ x = - 2$

hope this helps

Answer 2

Answer:

The value of x is -2.

Step-by-step explanation:

First, you have to eliminate the brackets by expanding :

$2(x - 4) = 4(2x + 1)$

$2x - 8 = 8x + 4$

Next, you have to move all the like-terms to one side :

$2x - 8 - 8x = 4$

$- 6x = 4 + 8$

$- 6x = 12$

$x = 12 \div ( - 6)$

$x = - 2$
