Ten less than half of a number(x) is 6.
Likurg_2 [28]

Answer:

x = 32

Step-by-step explanation:

Given the following data;

Unknown number = x

Translating the word problem into an algebraic equation, we have;

\frac {x}{2} - 10 = 6

Lowest common denominator (LCD) = 2

We multiply all through by 2;

2* \frac {x}{2} - 2*10 = 2*6

x - 20 = 12

x = 12 + 20

x = 32

Therefore, the unknown number is 32.
