Answer 1

Answer:

z = - 21/2

Step-by-step explanation:

let the number be z.

then, according to question,

3(-8/3) - z= 5/2

-z= 5/2 - 3(-8/3)

z= - [ 5/2 - 3 (-8/3)]

z= - [ 5/2 - 3 x -8/3]

z= - [ 5/2 + 8]

z= - [21/2]

z = - 21/2

Answer 2

Answer:

z = - 21/2

Step-by-step explanation:

let the number be z.

then, according to question,

3(-8/3) - z= 5/2

z= - [ 5/2 - 3 (-8/3)]

z= - [ 5/2 - 3 x -8/3]

z= - [ 5/2 + 8]

z= - [21/2]

z = - 21/2
