Final answer:
To solve for the unknown number, divide the sum of 8 and half of the number by 2, and set it equal to -6. Simplify the equation to find the value of the unknown number, which is -28.
Step-by-step explanation:
To solve the equation, we can represent the unknown number as x. The problem states that the sum of half of the number and 8 is -6, so we can translate this to the equation (1/2)x + 8 = -6. To isolate x, we can subtract 8 from both sides of the equation, resulting in (1/2)x = -14. Then, we can multiply both sides of the equation by 2 to get rid of the fraction, giving us x = -28.
