z każdego z podanych niżej wzorów wyznacz x a) P=abx b) y=2t-3x c) y=2(x-1)

a) x=P:ab b) y=2t-3x 3x=2t-y x= 2/3t - 1/3y c) y=2(x-1) y=2x-2 2x=y+2 x=1/2y+1

a) P = abx |:ab P:ab = x x = P/ab b) y = 2t-3x |+3x y+3x = 2t |-y 3x = 2t-y |:3 x = (2t-y)/3 c) y = 2(x-1) y = 2x-2 |+2 y+2 = 2x 2x = y+2 |:2 x = (y+2)/2 x = 0,5y+1
