Algebra Basics Solve the equation. Check your solution.
(Lessons 2.5, 2.6)
$d - 10 = 10$

Short Answer

Expert verified

The value of the variable is $d = 20$ .

Step by step solution

Step 1 . Add 14.

To find the value of variable c in the equation $d - 10 = 10$ $d - 10 = 10$ , add 14 from both sides of the equation.

$d - 10 + (10) = 10 + (10)$

Step 2 . Collect like terms.

Remove all the brackets and collect the like terms.

$d - 10 + 10 = 10 + 10$

Step 3 . Simplify the equation.

To further simplify, combine the like terms.

$\begin{matrix} d - 10 + 10 = 10 + 10 \\ d + 0 = 20 \\ d = 20 \end{matrix}$

Step 4 .Verify the value.

In order to verify the value of variable d, substitute 20 for d into the equation $d - 10 = 10$ .

$\begin{matrix} (20) - 10 = 10 \\ 10 = 10 True \end{matrix}$

Hence, the value of the variable is $d = 20$ .
