Question

if x= 4/7 y= -7/12 and z= -2/3 then verify that x-(y-z) not equal (x-y)-z​

Answer 1

Answer:

Step-by-step explanation:

x=4/7

y=-7/12

z=-2/3

x-(y-z)=4/7-(-7/12+2/3)

4/7-(2/3-7/12)

4/7-(8-7/12)

4/7-1/12=48-7/84

47/84

(x-y)-z=(4/7-(-7/12))-(-2/3)

((4/7+7/12)+2/3)

97/84+2/3

=97+30/84

=127/84

then x-(y-z) not equal to (x-y)-z
