- 8m = D - n

m = ( D - n ) / 8

a = P + b + 800 - you have to ask yourself, what's stopping the variable I want from being isolated?

d = n + 8m

you want to solve for m. First of all, n is being added to it. We're going to do the opposite of that to both sides in order to cancel out n, so SUBTRACT n from both sides:

d - n = n - n + 8m

d - n = 0n + 8m

d - n = 8m

Now what's stopping m from being isolated? It's being mutliplied by 8. So DIVIDE BOTH SIDES BY 8:

(d-n)/8 = 8m/8

(d-n) / 8 = (8/8)(m/1)

(d-n) / 8 = 1(m)

(d-n) / 8 = m

p = a - b - 8

p + b + 8 = a00
