Decide Whether the Equation Is an Identity, a Conditional Equation $- 0.2 ( x + 9 ) + 0.4 ( x + 9 ) = 0.2 x + 1.8$

Question 49

Multiple Choice

Decide whether the equation is an identity, a conditional equation, or a contradiction. Give the solution set.
- $- 0.2 ( x + 9 ) + 0.4 ( x + 9 ) = 0.2 x + 1.8$

A) Contradiction; $\varnothing$
B) Conditional; $\{ 0.2 \}$
C) Conditional; $\{ - 9 \}$
D) Identity; {all real numbers }

Decide Whether the Equation Is an Identity, a Conditional Equation −0.2(x+9)+0.4(x+9)=0.2x+1.8- 0.2 ( x + 9 ) + 0.4 ( x + 9 ) = 0.2 x + 1.8−0.2(x+9)+0.4(x+9)=0.2x+1.8
