Answer:

x = 4

Explanation:

Three less than half of a number is -1

The Half Of A Number means the number can be anything, so we can use "x." However, it is half so it would become: 1/2x.

Three less than means it is minus three, therefore becomes: 1/2x-3

However, three less than half of a number is (or in other words is equal too) -1, so the overall equation is

1/2x - 3 = -1

first, add three on both sides to get:

1/2x = 2

multiply two on both sides to get:

x = 4
