b) Tabx = 1
Tab = x
c) y=3x = 2t
3x = 2t-y
x = (2t-y)/3
d) y/2 = x-1
y/2 +1 = x
e) 2y = x-1
2y + 1 = x (tu potraktowałem, ze (x-1) dzielone jest przez 2, a nie x - (1/2) )
f) y (x-1) = 2
yx - y = 2
x-1 = 2/y
x = (2/y) + 1
g) P = 1/3a[kw] + 2/3ax
3P = a[kw] + 2ax
3P - 2ax = a[kw]
-2ax = a[kw] - 3P
2x = - ( [a[kw] - 3P]/a)
x = - ( [a- 3P/a]/2 )
