Decide Whether the Equation Is an Identity, a Conditional Equation $- 2 ( x + 7 ) + ( - 5 x ) = - 7 ( x - 7 ) + 5$

Question 220

Multiple Choice

Decide whether the equation is an identity, a conditional equation, or a contradiction. Give the solution set.
- $- 2 ( x + 7 ) + ( - 5 x ) = - 7 ( x - 7 ) + 5$

A) Contradiction; $\varnothing$
B) Conditional; $\{ 5 \}$
C) Conditional; $\{ 0 \}$
D) Identity; \{all real numbers\}

Decide Whether the Equation Is an Identity, a Conditional Equation −2(x+7)+(−5x)=−7(x−7)+5- 2 ( x + 7 ) + ( - 5 x ) = - 7 ( x - 7 ) + 5−2(x+7)+(−5x)=−7(x−7)+5
