1. P = a × t / 9 | : t/9
a=9P/t

2. Sx = t/a | * a
Sx*a=t | : Sx
a=t/Sx

3. gh = m/c+a
jesli
gh = (m/c)+a
a=gh-m/c

jesli
gh = m/(c+a) | * c+a
(c+a)*gh=m | : gh
c+a=m/gh
a=(m/gh)-c

4. (c+a) × b = d (a - c)
cb+ab=da-dc
ad-ab=cb+dc
a(d-b)=cb+dc | : (d-b)
a=(cb+dc)/(d-b)

1. P=a x t /9 x9
9P = a x t /t
9P/t = a

2. Sx = t/a x a
Sxa = t /Sx
a = t/Sx

3. gh = m/(c+a) x (c+a)
gh(c+a) = m /gh
c+a = m/gh
a = m/gh - c

4. (c+a) × b = d (a - c)
cb+ab=da-dc
ad-ab=cb+dc
a(d-b)=cb+dc | : (d-b)
a=(cb+dc)/(d-b)

5. ya = s + a /b
a = s + a/by
