Hi,

For this question, we need to solve for m alone by first adding 5m to both sides of the equation to get:

9m = -27

Now, undo the operation being done to m by dividing both sides by 9 to get:

m = -3 <==== FINAL ANSWER or Choice D

I hope that helps you out! Please let me know if you have any other questions!

Sincerely,

Andrew

You want to rearrange the equation so it starts out "m =". Start by moving all the m terms to the same side of the equals sign:

Add -5m to both sides of
     4m = -5m - 27
to get
     9m = -27

Then divide both sides by 9 so m has a coefficient of 1:
     m = -3

-4m-5m>27 -9m > 27 including -4m+ -5m -9m > 27 (divide the two facets with the aid of -9m to isolate m) -9m - 9m m <-3 (very final answer) word: continuously turn inequality sign while dividing with the aid of a adverse huge type solid success!! :)

4m = -- 5m -- 27
=> 4m + 5m = -- 27
=> 9m = -- 27
=> m = -- 27/9
=> m = -- 3 [ D is true.]

Hi,
Item D is the correct answer. Find that as follows:
4m = -5m -27
5m +4m = -27........(Add 5m to each side of the equation.)
9m = -27 .........(Combine like terms.)
m = -27/3 .........(Divide each side of the equation by 3.)
m = -3.........(Result of the division.)

4m = -5m - 27
4m+5m=-5m-27+5m
9m=-27
9m/9=-27/9
m=-3
option D.

4m = -5m - 27
4m + 5m = -5 + 5m -27
9m = - 27
9m/9 = -27/9
m = -3

4m = -5m -27


4m = -5m -27
9m = -27
m = -3

-5m contains the variable to solve for, move it to the left-hand side of the equation by adding 5m to both sides.
4m+5m=-27

4m and 5m are like terms, add 5m to 4m to get 9m.
9m=-27

Divide each term in the equation by 9.
(9m)/(9)=-(27)/(9)

Simplify the left-hand side of the equation by canceling the common terms.
m=-(27)/(9)

Simplify the right-hand side of the equation by simplifying each term.
m=-3

answer is "d".
