Question

the sum of two rational number is -5 if one of them is - 17 by 16 what is the other​

Answer 1

Answer:

Given a fixed number zz, you can take each q∈Qq∈Q and find the unique yq∈Ryq∈R such that z+yq=qz+yq=q. Since each yqyq is unique, clearly there are only countably many numbers with that can be found.

So out of the entire pool of |R||R| things that can go into the yy of "z+yz+y", only countably many will yield a rational 

Answer 2

Answer:

x = -63/16

Step-by-step explanation:

let number be x

according to question

(x) + (-17/16) = -5

=> x = -5 + 17/16

taking LCM on RHS

=> x = { (-5×16) + (17×1) } ÷ 16

=> x = (-80+17)/16

=> x = -63/16
