cho a+b=c+d=e+f voi a, b , c ,d,e,f la cac so nguyen phan biet nho hon 20 tim a+b

a, Cho F(x)  = a x+b . Tim a,b biet f(0) = 3 va  F(2) =-1

b, Cho F(x) =a x+ b. Tim a,b biet F(1) = -1 va F(-2) = 8 

c, Cho F(x) =a x +b .tim a,b biet F(0) = 1 va F(-2) = -9

1: tim a,b biet

a,b=b,a*3+1,3

2: tim cac chu so a,b,c,d biet:

a=b+1

(a,b+1,5)*c.d=14,4

(a,b+0,5)*c,d

tim a,b,c biet

0,a+a,b+ab,c=bc,b

giup toi voi

cho a=-4, b-c= -9 . tim A biet A^2 = b.(a-c)-c.(a-b)

cho a=-4, b=-9 . tim A biet A^2 = b.(a-c)-c.(a-b)

cho a=-4, b=-9 . tim A biet A^2 = b.(a-c)-c.(a-b)

cho a=-4, b=-9 . tim A biet A^2 = b.(a-c)-c.(a-b)

cho 3 so tu nhien A,B va C biet,B=1/5 A ,C=1/18 A va biet B chia cho C du 21.Tim so tu nhien A
