-30 + 5x is less than or equal to 4(8x +6)

1 answer

To solve the inequality \(-30 + 5x \leq 4(8x + 6)\), we can follow these steps:

  1. Distribute on the right side: \[ 4(8x + 6) = 32x + 24 \] So the inequality becomes: \[ -30 + 5x \leq 32x + 24 \]

  2. Move all terms involving \(x\) to one side and constant terms to the other side. We can subtract \(5x\) from both sides: \[ -30 \leq 32x - 5x + 24 \] This simplifies to: \[ -30 \leq 27x + 24 \]

  3. Next, subtract 24 from both sides: \[ -30 - 24 \leq 27x \] Which simplifies to: \[ -54 \leq 27x \]

  4. Now divide both sides by 27: \[ \frac{-54}{27} \leq x \] Simplifying \(\frac{-54}{27}\): \[ -2 \leq x \]

  5. This can be rewritten as: \[ x \geq -2 \]

Therefore, the solution to the inequality is: \[ x \geq -2 \]
