13+d=44 What does the variable represent

13+d=44

d = 44 - 13
d = ?

d = 31 Thank you Ms. Sue

You're welcome, Joseph.

In the equation 13 + d = 44, the variable "d" represents the unknown value that when added to 13 equals 44. To find the value of "d," you can solve the equation by isolating the variable on one side of the equation.

To do that, you need to perform the inverse operation of addition, which is subtraction, in order to isolate the variable "d" on one side of the equation. Here are the steps to solve the equation:

1. Start with the original equation: 13 + d = 44.
2. To isolate the variable "d," subtract 13 from both sides of the equation:
13 - 13 + d = 44 - 13 (subtracting 13 from both sides)
Simplify: d = 31

Therefore, the variable "d" represents the value 31, as substituting it into the equation results in a true statement: 13 + 31 = 44.
