xyz = m solve for y
c = 5p + 215 solve for p
0.4x  0.2 = 1
 Please and thank you for the help.

1. g + b = y
g + g + b = y + g
0 + b = y + g
b = y + g
2. a/b = c
b(a/b) = bc
(b/b)(a) = bc
1(a) = bc
a = bc
3. Same as number 2.
4. x/y + k = p
x/y + k  k = p  k
x/y + 0 = p  k
x/y = p  k
y(x/y) = y(p  k)
(y/y)(x) = y(p  k)
1(x) = y(p  k)
x = y(p  k)
5. xyz = m
yxz = m
(yxz)/(xz) = m/(xz)
y = m/(xz)
6. c = 5p + 215
c  215 = 5p + 215  215
c  215 = 5p + 0
c  215 = 5p
(c  215)/5 = 5p/5
(c  215)/5 = p
7. 0.4x  0.2 = 1
0.4x  0.2 + 0.2 = 1 + 0.2
0.4x + 0 = 1.02
0.4x = 1.02
0.4x/0.4 = 1.02/4
x = 0.255
