Answer: D) 18

Step-by-step explanation:

6 - x = -12

Subtract 6 from both sides.

-x = -18

Divide by -1 on both sides so as to isolate x.

x = 18

Answer:

D. 18

Step-by-step explanation:

The first thing you need to do is subtract 6 from both sides. This makes it cancel out on the left, since 6 - 6 = 0, and subtract 6 from -12:

6 − x = −12

-6 - 6

________

-x = -18

Then divide both sides by -1, because there's a negative sign (-) in front of the x, meaning there's like an invisible 1 there:

-1x = -18

x = 18

What are the corresponding steps used to find the product of (2x+1)(x+1) ?

expeople1 [14]

You would distribute the 2x to the x and 1= 2x^2+2x
then you would distribute the 1 to the x and 1= 1x+1
then you would add it all together to get
2x^2+3x+1

Write each fraction as a sum or difference 14-6x/19

Oksanka [162]

Given number : 14 - 6x / 19
So we need to write this fraction as a sum or difference.
First, simplify the given number:
=> 14 – 6x / 19
=> 14 x 19 – (6x)
 19
=> 266 – 6x
 19
=> 266 – 6x = -2 * (3x - 133)
Thus, the final result would be:
=> -2 * (3x - 133) => This will be the fraction sum or difference of the given number
 19
