Question

Solve for m: To figure out how they got the answer , they got.

Answer 1

Answer:

M = 90

Step-by-step explanation:

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

$- \frac{2m}{9} + 12 = - 8$

2) Subtract 12 from both sides.

$- \frac{2m}{9} = - 8 - 12$

3) Simplify - 8 - 12 to -20.

$- \frac{2m}{9} = - 20$

4) Multiply both sides by 9.

$- 2m = - 20 \times 9$

5) Simplify 20 × 9 to 180.

$- 2m = - 180$

6) Diving both sides by -2.

$m = \frac{ - 180}{ - 2}$

7) Two negative makes a positive.

$m = \frac{180}{2}$

8) Simplify 180/2 to 20.

$m = 90$

Hence, the answer for m is m = 90

Answer 2

Answer:

m = 90

Step-by-step 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 :)
