Answer:

M = 90

Explanation:

1) Simplify 2/9m to 2m/9.


- (2m)/(9) + 12 = - 8

2) Subtract 12 from both sides.


- (2m)/(9) = - 8 - 12

3) Simplify - 8 - 12 to -20.


- (2m)/(9) = - 20

4) Multiply both sides by 9.


- 2m = - 20 * 9

5) Simplify 20 × 9 to 180.


- 2m = - 180

6) Diving both sides by -2.


m = ( - 180)/( - 2)

7) Two negative makes a positive.


m = (180)/(2)

8) Simplify 180/2 to 20.


m = 90

Hence, the answer for m is m = 90

Answer:

m = 90

Explanation:

Hi,

To begin, you have to isolate the variable, m, meaning that we have to first, subtract 12 on both sides.

-2/9m = -20

Now, instead of dividing by -2/9, we can multiply -20 by -9/2 to find m. (All you have to do is flip the fraction). When we do this...

-20/1 x -9/2 = 180/2 = 90

m = 90

I hope this helps :)
