solve the equation for m

Please look at what I assumed your equation was:  .

Step-by-step explanation:

I'm going to pretend that says:

.

Please correct me if I'm wrong.

We want to solve for M.

The very first thing I'm going to do is multiply both sides by .

Now I'm going to divide both sides by -kn:

Simplifying:

Sometimes people don't like the negative on bottom; just move it to the center:

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
