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
