Question

Oblicz wartość wyrażenia :

6x - 1 a) x =0

6x - 1 b) x = -1

6x - 1 c) x = jedna trzecia

6x - 1 d) x = jeden i jedna druga

6x - 1 e) x = 1,8

Answer 1

a) 6*0-1 = 0-1 = -1

b) 6*(-1)-1 = -6-(-1) = 5 

c) 6*1/3-1 = 6/1*1/3 = 2/1 = 2-(-1) = 2

d) 6*1i 1/2-1 = 6/1*3/2=9/1=9-(-1) = 8

e) 6*1,8-1= 10,8-1=9,8

Answer 2

6*0-1= 0-1=-1

6*(-1) -1=-6-1= -7

6*1/3-1=2-1=1

6*1 1/2 -1 =6*3/2 -1= 6-1=5

6*1,8 -1 = 10,8 -1=9.8
