Quizplus · Accepted Answer

The equation $|x| + 7 = 16$ simplifies to $|x| = 9$, which means $x = 9$ or $x = -9$, hence the solution set is $\{-9, 9\}$.

Solve the Given Equation or Inequality ∣x∣+7=16|x|+7=16∣x∣+7=16 A) {−16}\{-16\}{−16} B) {9}\{9\}{9} C) {−9,9}\{-9,9\}{−9,9} D) {−16,16}\{-16,16\}{−16,16}

Solve the Given Equation or Inequality $|x|+7=16$ A) $\{-16\}$ B) $\{9\}$ C) $\{-9,9\}$ D) $\{-16,16\}$
