Chapter 3.1, Problem 43E

To determine

To find: and check the solution of the expression x−17=−45 .

Expert Solution & Answer

Answer to Problem 43E

The answer after evaluating the expression x−17=−45 is x=−28 .

Explanation of Solution

Given information: Consider the equation given to find and check the solution of the expression x−17=−45 .

Calculation :

Subtracting the same number from each side of the equation that produces an equivalent equation,

x−17=−45 [Write original equation.]x−17−17=−45−17 [Subtract 17 from each side.]x=−28 [Simplify.]

Hence, the solution is −28 .

Check the solution,

x−17=−45 [Write original equation.]−28−17=−45 [Substitute−28 for x.]
