Question

zapisz w jak najprostszej postaci:

b) 10 - 2 ( t + 1 )

c) -3 ( 2y + 1/3) + 4y

d) -6 ( 1 - 0,5u + 3u/2

e) 2 ( 3w - 1) - w+2/2

f) 3 ( a - 2b) - 5 ( b -2a)

please bo nie kumam tego :(

Answer 1

b) 10 - 2 ( t + 1 ) = 8(t+1)= 8t+8

c) -3 ( 2y + 1/3) + 4y= -6y-1+4y= -2y-1

d) -6 ( 1 - 0,5u + 3u/2 )= -6+3u- 18u/2= -6+3u-9u= -6-6u

e) 2 ( 3w - 1) - w+2/2 = 6w-2-w+1= 5w-1

f) 3 ( a - 2b) -  5 ( b -2a)= 3a-6b-5b+10a= 13a-11b
