Explanation Given Information: The provided inequality is | 7 x + 3 | ≤ 0 . Calculation: Consider the inequality | 7 x + 3 | ≤ 0 . Since, the absolute value of an expression is always nonnegative (positive or zero), so the inequality is true only when 7 x + 3 = 0 . Add − 3 to both the sides; 7 x + 3 − 3 = 0 − 3 7 x = − 3 Divide both sides by 7 ; 7 x 7 = − 3 7 x = − 3 7 In order to check, Put x = − 3 7 in the equation 7 x + 3 = 0
