Question

Solve the inequality: -2x + 7 < 23

Answer 1

Explanation:

`= - 2x + 7 < 23`.

Move the constant to the right side..

`= - 2x < 23 - 7`

Subtract 7 from 23

`= - 2x < 16`

Change the symbol and reverse the symbol of the inequality to other direction...

`= 2x > - 16`

Now....divide both side by the same number

`= x > - 8`

Answer 2

x > -8

Explanation:

-2x + 7 < 23

Subtract 7 from each side

-2x + 7-7 < 23-7

-2x < 16

Divide by -2, remembering to flip the inequality

-2x/-2 > 16/-2

x >-8
