Half the sum of a number and 10 is 8. Find the number.

Question

3

6

2

-2

Answer 1

Let's represent the number as x.
The given equation can be written as the following equation: (1/2)(x + 10) = 8.
Multiplying both sides by 2 to get rid of the fraction, we have x + 10 = 16.
Subtracting 10 from both sides, we get x = 6.
Therefore, the number is 6.
