Answer:

Only option E is equivalent to $5x+6=-8x-18$ .

Step-by-step explanation:

Given the expression

(5x+6) over 2 = 3-(4x + 12)

Let us simplify the expression

$\frac{\left(5x+6\right)}{2}=3-\left(4x+12\right)$

Multiply both sides by 2

$\frac{5x+6}{2}\cdot \:2=3\cdot \:2-\left(4x+12\right)\cdot \:2$

$5x+6=6-\left(4x+12\right)\cdot \:2$

Expand -(4x + 12) = -4x - 12

$5x+6=-8x-18$

Thus, option E is equivalent to $5x+6=-8x-18$ .

Further solving

$5x+6=-8x-18$

Add 8x from to both sides

$5x+8x=-8x-24+8x$

Simplify

$13x=-24$

Divide both sides

$\frac{13x}{13}=\frac{-24}{13}$

Simplify

$x=-\frac{24}{13}$

Thus, only option E is equivalent to $5x+6=-8x-18$ .

Answer:

We can check this two ways: distributing the -0.5, and plugging in a number for x.

First, we can check this by distributing the -0.5. Our equation becomes:

-1.5x -2.5 = -1.5x + 2.5

Clearly, this is not true. We can show this one more time by plugging in a number for x. I will use 2.

Now, we evaluate both sides and see if they are equal.

-3 - 2.5 = -3 + 2.5

-5.5 = 0.5

Clearly, this is not true. These expressions are not equivalent.
