The solution set is all real numbers less than 4, expressed as \( \{x \mid x < 4\} \) or in interval notation as \( (-\infty, 4) \).

Solución

We start with the inequality:   8(x + 5) – 4x > 7(x – 1) + 35 Step 1. Distribute on both sides:   LHS: 8(x + 5) – 4x = 8x + 40 – 4x = 4x + 40   RHS: 7(x – 1) + 35 = 7x – 7 + 35 = 7x + 28 So the inequality becomes:   4x + 40 > 7x + 28 Step 2. Isolate the variable x:   Subtract 4x from both sides:    40 > 3x + 28   Subtract 28 from both sides:    12 > 3x   Divide both sides by 3:    4 > x This can be rewritten as:   x < 4 Step 3. Express the solution in the requested forms: Set-builder notation:   {x ∈ ℝ | x < 4} Interval notation:   (–∞, 4) Graphing the solution: On a number line, draw an open circle at 4 (since 4 is not included) and shade the line extending to the left toward negative infinity. Thus, the final answer is:   Set-builder: {x ∈ ℝ | x < 4}   Interval: (–∞, 4)

Let's solve the inequality step-by-step and then express the solution set. First, we simplify the inequality: \[ 8(x + 5) - 4x > 7(x - 1) + 35 \] Expanding both sides: \[ 8x + 40 - 4x > 7x - 7 + 35 \] \[ 4x + 40 > 7x + 28 \] Now, we isolate \(x\): \[ 40 - 28 > 7x - 4x \] \[ 12 > 3x \] Dividing both sides by 3: \[ 4 > x \] or \[ x < 4 \] Expressing the solution set in set-builder notation: \[ \{x \mid x < 4\} \] Now, in interval notation, the solution set is: \[ (-\infty, 4) \] Graphically, you would represent this on a number line with an open circle at 4 and a line extending to the left towards negative infinity to indicate that all values less than 4 are included in the solution set.
