a)
a = bc - d
bc = a + d /:b
b ≠ 0
c = (a + d)/b
b)
a = bc + d
bc = a - d /:b
c = (a - d)/b
c)
a = c(b - d) /:(b - d)
(b - d) ≠ 0
c = a/(b - d)
d)
a = (b + c)/d /*d
b + c = ad
c = ad - b
e)
a = (b - c)/d /*d
b - c = ad
-c = ad - b /*(-1)
c = b - ad
f)
a = b/(c + d) /*(c + d)
a(c + d) = b /:a
a ≠ 0
c + d = b/a
c = b/a - d
g)
a = b/(c - d) /*(c - d)
a(c - d) = b
ac - ad = b
ac = b + ad /:a
c = (b + ad)/a
h)
a = b - c/d
a + c/d = b
c/d = b - a /*d
c = d(b - a)
i)
a = b/c + d
a - d = b/c
c(a - d) = b /: (a - d)
a - d ≠ 0
c = b/(a - d)
