Question

The sum of twelve and half of a number is -5

Answer 1

n = -34

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 +
`(n)/(2)` is -5

12 +
`(n)/(2)` = -5

[] Now that we have a mathematical equation, we can solve for n

-> Given

12 +
`(n)/(2)` = -5

-> Multiply both sides of the equation by 2

24 + n = -10

-> Subtract 24 from both sides

n = -34
