Question

If -12-4(-2x)= 4 then what is x?

Answer 1

Answer:

$\boxed{\boxed{\sf x=2}}$

Step-by-step explanation:

$\sf -12-4\left(-2x\right)=\:4$

First, let's remove parentheses:

$\sf -12-4\times -2x=4$

Simplify, multiply, 4 * -2x = -8x:

$\sf -12-(-8x)=4$

** Apply rule: - ( -a )= a

$\sf 12+8x=4$

Now, let's regroup terms

$\sf 8x-12=4$

Add 12 to both sides:

$\sf -12+8x+12=4+12$

Simplify, 4 + 12= 16

$\sf 8x=16$

Divide both sides by 8:

$\sf \cfrac{8x}{8}=\cfrac{16}{8}$

$\sf x=2$

Answer 2

Answer:

$hey \: buddy \: \\ this \: is \: your \: answer$

Step-by-step explanation:

1)Eliminate redundant parentheses

$- 12 - 4( - 2x) = 4 \\ - 12 - 4( - 2x) = 4$

2)Multiply the numbers

$- 12 - 4( - 2)x = 4 \\ - 12 + 8x = 4$

3)Rearrange terms

$- 12 + 8x =4 \\ 8x - 12 = 4$

4)Simplify the equation

$8x = 12 + 4 \\ 8x = 16 \\ 8x \div 8 = 16 \div 8$

5) Divide

$x = 2$
