1. 4d - p = m
(4d - p) + p = (m) + p
4d/4 = m + p/4
d = m+p/4
2. 1/5v + gt = a
(1/5v + gt) - gt = (a) - gt
(1/5v)5 = (a - gt)5
v = 5(a - gt)
3. D = rt
D/r = rt/r
t = D/r
4. 2wy - 8n = 4k
(2wy - 8n) + 8n = (4k) + 8n
2wy/2y = 4k + 8n/2y
w = 4k+8n/2y
w = 2k+4n/y
5. (Number cut off)
6. bg + 9f = 27
bg + 9f/9 = 27/9
(bg + f) - f = (3) - f
bg/b = 3 - f/b
g = 3-f/b
