Question

2x – 7 < 4, x € {1, 2, 3, 4, 5, 6, 7}​

Answer 1

Answer:

2x-7<4

2x<7+4

2x<11

x=11/2=5.5

x={1,2,3,4,5}

Answer 2

x = {1, 2, 3, 4, 5}  

Given:

2x – 7 < 4, x € {1, 2, 3, 4, 5, 6, 7}​

To find:

Solve the equation and find x values

Solution:

Given 2x – 7 < 4

We can solve the given equation as shown below

⇒ 2x – 7 < 4  

⇒ 2x < 4 +7

⇒ 2x < 11

⇒ x < 11/2

⇒ x < 5.5

given that  x € {1, 2, 3, 4, 5, 6, 7}​

And x is less than 5.5

⇒ x values are {1, 2, 3, 4, 5}  

Therefore,

x = {1, 2, 3, 4, 5}
