Answer:

<h2>Only one solution</h2>

Step-by-step explanation:

Solution,

- 6(x + 7) =  - 4x - 2

Distribute -6 through the parentheses

- 6x - 42 =  - 4x - 2

Move variable to L.H.S and change its sign

- 6x + 4x  - 42 =  - 2

Move constant to R.H.S and change its sign

- 6x + 4x =  - 2 + 42

Collect like terms

- 2x  =  - 2 + 42

Calculate the sum

- 2 x = 40

Divide both sides of the equation by - 2

\frac{ - 2x}{ - 2}  =  \frac{40}{ - 2}

Calculate

x =  - 20

Hope this helps..

Good luck on your assignment..

Help !? Pls, don’t understand math that much
Arlecino [84]
Day 1: $2.70 is added to the value of the share. 
           $43.85 + $2.70 = $46.55 

Day 2: $2.70 is added to the value of the share. 
           $46.55 + $2.70 = $49.25

Day 3: $1.10 is subtracted from the value of the share. 
           $49.25 - $1.10 = $48.15 

Day 4: $1.10 is subtracted from the value of the share. 
           $48.15 - $1.10 = $47.05 

Day 5: $4.45 is subtracted from the value of the share. 
           $47.05 - $4.45 = $42.60 

After 5 days, the value is $42.60, which is choice B. 
Hope this helps!
