Concept:To solve a linear inequality, simplify the bracket first, collect like terms, and then isolate x using inverse operations.Solution:The minus sign outside the bracket changes the sign of every term inside it:−(3x+4)=−3x−4.So the inequality becomes:3−3x−4≤−4.Combine the constant terms: 3−4=−1.Thus, −1−3x≤−4.Add 1 to both sides to get:−3x≤−3.Now divide both sides by −3.Because we divide by a negative number, the inequality sign reverses:x≥1.Answer:Option B (x≥1)
