You purchase 4 videos. The original price of each video is x dollars You decide to purchase the limited edition version of the videos for an additional cost. your cost is (4x±20) dollars what can you conclude about the additional; cost limited edition version of the video

The limited edition cost additional $5 per videos

Solution:

Given that,

you purchase 4 videos

The original price of each video is x dollars

Therefore,

Cost of 4 videos = 4x dollars

You decide to purchase the limited edition version of the videos for an additional cost

your cost is (4x ± 20) dollars

So, total additional cost is $20

We are purchasing 4 videos

Therefore,

so, additional cost in each videos is $ 5

Thus the limited edition cost additional $5 per videos

Which means, when you purchase limited edition version of the videos, it adds up $ 5 for each video to original cost of each video

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
