Solve for w.<br> - 2w – 14= 2(w+1)<br> Simplify your answer as much
snow_tiger [21]

Answer:

w = -4

Step-by-step explanation:

<u>Step 1:  Distribute</u>

-2w - 14 = 2(w + 1)

-2w - 14 = 2w + 2

<u>Step 2:  Add 2w to both sides</u>

-2w - 14 + 2w = 2w + 2 + 2w

-14 = 4w + 2

<u>Step 3:  Subtract 2 from both sides</u>

-14 - 2 = 4w + 2 - 2

-16 = 4w

<u>Step 4:  Divide both sides by 4</u>

-16 / 4 = 4w / 4

<em>-4 = w</em>

<em />

Answer:  w = -4

What is the answer for |x|=9
Maru [420]

The absolute value |x| returns the "positive version" of a number.

In other words, if the number is positive, it remains positive; if the number is negative, it changes sign.

So, if we want |x|=9, we want the "positive version" of x to be 9.

This can happen in two ways: if x is already 9, then its absolute value is still nine. If instead x=-9, its positive value will be 9 again.

In formula, we have

|x|=9 \iff x=\pm 9

because

|9|=9,\quad |-9|=9
