Question

List the solution set of 30-4(2x-1) =30, given that x is a positive integer​

Answer 1

Answer:

Given inequation,

30−4(2x−1)<30

⇒30−8x+4<30

⇒34−8x<30

⇒−8x<30−34

⇒−8x<−4

⇒8x>4[On multiplying both sides by -1, the inequality reverses]

⇒x>4/8

⇒x>1/2

As x is a positive integer

The solution set is {1,2,3,…}

Answer 2

Step-by-step explanation:

Given equation:

30 - 4(2x - 1) =30

Solving:

30 - 4(2x - 1) = 30

30 - 8x + 4 = 30

34 - 8x = 30

34 - 30 = 8x

4 = 8x

4/8 = x

1/2 = X
