How do you solve the inequality 5(x - 8) < 5?
Back
First, distribute: 5x - 40 < 5. Then, add 40 to both sides: 5x < 45. Finally, divide by 5: x < 9.

Front
Is x = 9 a solution to the inequality x > 9?
Back
No, x = 9 is not a solution because it does not satisfy the condition of being greater than 9.

Front
How do you solve the inequality -4x + 14 ≤ 54?
Back
Subtract 14 from both sides: -4x ≤ 40. Then, divide by -4 (remember to flip the inequality): x ≥ -10.

Front
What is the solution to the inequality x + 5 ≤ 13?
Back
Subtract 5 from both sides: x ≤ 8.

Front
How do you solve the inequality -20 > 18 + m?
Back
Subtract 18 from both sides: -38 > m, or m < -38.
