The difference of half of a number and three is equivalent to negative five?
swat32

Answer:

-7

Step-by-step explanation:

Let the number be represented with 'Y'

Half of the number will be = Y/2

The difference of half of a number and 3

= Y/2 - 3

Is equivalent to negative 5

That is,

Y/2 - 3 = -5

y/2-3/1 = -5/1

Collect like terms

y/2 = -5/1+3/2

y/2 = -7/2

Multiply both sides by 2

y/2 ×2 = -7/2×2

Y = - 7

Hence the number is negative 7
