Decide whether the equation is an identity, a conditional equation, or a contradiction. Give the solution set.
-$$4 ( 16 x + 20 ) = 16 ( 2 x - 13 )$$
A) Contradiction; $\varnothing$
B) Identity; \{all real numbers $\}$
C) Conditional; $\{ 4 \}$
D) Conditional; $\{ - 9 \}$

Question

Quizplus · Accepted Answer

Simplifying both sides of the equation gives a conditional equation with a single solution, x = -9.

Decide Whether the Equation Is an Identity, a Conditional Equation 4(16x+20)=16(2x−13)4 ( 16 x + 20 ) = 16 ( 2 x - 13 )4(16x+20)=16(2x−13)

Decide Whether the Equation Is an Identity, a Conditional Equation $4 ( 16 x + 20 ) = 16 ( 2 x - 13 )$
