Short Answer

Expert verified

The value of the variable is $c = 5$ .

Step by step solution

Step 1. Subtract 8.

To find the value of the variable c in the equation $8 + c = 13$ , subtract 8 from both sides of the equation.

$8 + c - (8) = 13 - (8)$

Step 2. Collect like terms.

Remove all the brackets and collect the like terms.

$c + 8 - 8 = 13 - 8$

Step 3. Simplify the equation.

To further simplify, combine the like terms.

$c + 8 - 8 = 13 - 8 c - 0 = 5 c = 5$

Step 4. Verify the value.

In order to verify the value, substitute 5 for c into the equation $8 + c = 13$ .

$8 + (5) = 13 13 = 13 True$

Hence, the value of the variable is $c = 5$ .
