Question

Of the following sets, which numbers in {1, 2, 3, 4, 5} make the inequality 3x + 1 > 4 true?

Answer 1

Answer:

{2, 3, 4, 5}

Step-by-step explanation:

3x + 1 > 4

3x > 3

x > 1.

If x = 1 the inequality is not true,

- but  2 3 4 and 5 will make the inequality true.

Answer 2

Answer:

{ 2, 3, 4, 5 }

Step-by-step explanation:

Firstly solve the inequality

3x + 1 > 4 ( subtract 1 from both sides )

3x > 3 ( divide both sides by 3 )

x > 1

From the set { 1, 2, 3, 4, 5 } then the values which make the inequality true are

{ 2, 3, 4, 5 }
