1.
a)
S = [tex]\frac{a + 2t}{3}[/tex] / *3
3S = a + 2t / -a
3S - a = 2t /:2
t = [tex]\frac{3S - a}{2}[/tex]
b)
F = [tex]\frac{4y - z}{3}[/tex] /*3
3F = 4y - z /+z
3F + z = 4y /-3F
z = 4y - 3F
c)
P = t - 3rt + 2 /+3rt
P + 3rt = t + 2 / -P
3rt = t + 2 - P /:3t
r = [tex]\frac{t + 2 - P}{3t}[/tex]
d)
a = [tex]\frac{4k - l}{m}[/tex] + 2 /*m
am = 4k - l + 2m /+l
am + l = 4k + 2m /-am
l = 4k + 2m -am
