Zapisz w jak najprostszej postaci: a)2x-(-4-3x) 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) BŁAGAM POTRZEBNE MI !!!

a)2x-(-4-3x)= 2x+4+3x=5x+4 b)10-2(t+1)= 10-2t-2=-2t+8 c)-3(2y+1/3)+4y= -6y-1+4y=-2y-1 d)-6(1-0,5u)+3u= -6+3u+3u=6u-6 2 e)2(3w-1)-w+2= 6w-2-w+2=5w 2 f)3(a-2b)-5(b-2a)=3a-6b-5b+10a=13a-11b

a) 2x-(-4-3x) = 2x+ 4 -3x= -1x + 4 b)10-2(t+1) = 10- 2t -2= 8- 2t c)-3(2y+1/3)+4y = -6y - 1 + 4y= -2y -1 d)-6(1-0,5u)+3u ---------------------- = 2 -6 + 3u + 3u = ---------------- = 2 -6 + 6u = ------------ = 2 = -3 + 3u e)2(3w-1)-w+2 ---------------------- = 2 6w -2 -w +2 = ----------------- = 2 = 5w :2 = 2,5 w f)3(a-2b)-5(b-2a) = 3a - 6b - 5b + 10a= 13a - 11b ;)

a) 2x-(-4-3x)= =2x+4+3x= =5x+4 b) 10-2(t+1)= =10-2t-2= =8-2t c) -3(2y+1/3)+4y= =-6y-1+4y= =-2y-1 d) -6(1-0,5u)+3u= =-6+3u+3u= =6u+6 e) 2(3w-1)-w+2= =6w-2-w+2= =5w f) 3(a-2b)-5(b-2a) =3a-6b-5b+10a= 13a-11b Prosze :))
