Answer:
n = -34
Step-by-step explanation:
[] The underlined portion is turned into a mathematical equation in the next line
-> n will represent "a number"
The sum of twelve and half of a number is -5
12 + and half of a number is -5
12 + [tex]\frac{n}{2}[/tex] is -5
12 + [tex]\frac{n}{2}[/tex] = -5
[] Now that we have a mathematical equation, we can solve for n
-> Given
12 + [tex]\frac{n}{2}[/tex] = -5
-> Multiply both sides of the equation by 2
24 + n = -10
-> Subtract 24 from both sides
n = -34
Have a nice day!
