Z każdego z podanych niżej wzorów wyznacz x ;
d.) T=1/abx
e.) y=2t-3x
f.) y=2(x-1 )
g.) y= x-1 / 2
h.) y=2/x-1
i.) P= 1/3 (a < do drugiej > + 2ax )
Proszę pomocy! ♥

Tabx = 1 | :Tab
x = 1/Tab
e) y=2t-3x | -2t
y - 2t = -3x | :(-3)
x = -(y - 2t)/3
f) y=2(x-1)
y = 2x - 2 | +2
y + 2 = 2x | :2
x = (y + 2)/2
g) y= x-1/2 |+1/2
x = y + 1/2
h) y= 2/x-1 |*x - 1
y(x - 1) = 2
yx - y = 2 |+y
yx = 2 + y | :y
x = (2 + y)/y
i) P=1/3 (a² +2ax )
P = 1/3a² + 2/3ax | -1/3a²
2/3ax = P - 1/3a² | :2/3a
x = (P - 1/3a²) / 2/3a
d) T=1/abx | *abx
Tabx = 1 | :Tab
x = 1/Tab
e) y=2t-3x | -2t
y - 2t = -3x | :(-3)
x = -(y - 2t)/3
f) y=2(x-1)
y = 2x - 2 | +2
y + 2 = 2x | :2
x = (y + 2)/2
g) y= x-1/2 |+1/2
x = y + 1/2
h) y= 2/x-1 |*x - 1
y(x - 1) = 2
yx - y = 2 |+y
yx = 2 + y | :y
x = (2 + y)/y
i) P=1/3 (a² +2ax )
P = 1/3a² + 2/3ax | -1/3a²
2/3ax = P - 1/3a² | :2/3a
x = (P - 1/3a²) / 2/3a
Strasznie trudne ale sobie poradziłem.Liczce na naj
