Determine if the following equation is a conditional equation, an identity, or a contradiction.- 5x – 15 = -3(x – 3) + 4AnswerKeyboaO ConditionalO IdentityO Contradiction

Respuesta :

Given the equation:

[tex]-5x-15=-3\mleft(x-3\mright)+4[/tex]

Solving this equation:

[tex]\begin{gathered} -5x-15=-3x+9+4 \\ -15-13=-3x+5x \\ 2x=-28 \\ \Rightarrow x=-14 \end{gathered}[/tex]

Then, the equation is only true for x = -14, and we conclude that it is a conditional equation.
