Hello, there!


5g - 30 = -40

We can solve this by working backwards.

First, let's isolate the g.

We will do this by adding 30 to each side.

5g - 30 = -40
+ 30 + 30

5g = 10

Finally, we will divide each side by 5 to get our final answer


(5g )/(5) = (10)/(5)

Our final answer is 2.

g = 2


16 - 7m = 30

We will use the same process as we did for the last question

Let's subtract 16 from each side to isolate the m

16 - 7m = 30
-16 -16

-7m = 14

Now, let's multiply each side by -1 to make m a positive number.

-7m = 14
* -1 *-1

Now, we have 7m = -14

We will now divide each side eby 7 to get our final answer.


(7m)/(7) = (-14)/(7)

Our final answer is -2

m = -2


I hope I helped!

Let me know if you need anything else!
