Question

for rational numbers x=-2/3 y=-7/4and z=5/12 check if the following state ments are correct. (a) x+y=y+z

Answer 1

Step-by-step explanation:

x= -2/3 y= -7/4 z=5/12

LHS=x+y

= -2/3+(-7/4)

= -2/3-7/4

=(-8-21)/12

= -29/12

RHS= y+z

= -7/4+5/12

=(-21+5)

= -16/12

so LHS is not equal to RHS

hence, x+y is not equal to y+z

so the statement is incorrect.
