Chapter 3: Q. 44 (page 122)

Algebra Basics Solve the equation. Check your solution. (Lesson 2.5)
$d - 22 = - 43$

Short Answer

Expert verified

The solution for the equation $d - 22 = - 43$ is $d = - 21$ .

Step by step solution

. Separate the variable and constants

Write the original equation and separate the variables.

$\begin{array}{l} d - 22 = - 43 [Writeoriginalequation.] \\ d - 22 + 22 = - 43 + 22 [Add22toeachside.] \end{array}$

. Simplify both sides

Simplify the equation on both sides to solve it.

$\begin{array}{l} d = - 43 + 22 \\ d = - 21 \end{array}$

Therefore, the solution of the equation is $d = - 21$ .

. Check the solution

To check the solution, write the original equation and substitute the value of d.

$d - 22 = - 43$

Now, substitute $d = - 21$ and check the result.

$\begin{array}{l} - 21 - 22 = - 43 [Substitute - 21 ford.] \\ - 43 = - 43 \end{array}$

As the left-hand side is equal to right hand side, this signifies that the solution is correct.
