Solve for x: - 2x + 5 < 7

-2x + 5 < 7

-2x + 5 < 7

-5 - 5 deduct 5 from both sides

-2x < 2

: - 2 : - 2 divide both sides by negative 2. Because of the division

x > - 1 using a negative number, the sign is then reversed.

from.

The value of x should be greater than - 1. It can be 0, 1, 2, so on ...

To check: Revert back to the original sign which is <.

x = 1

-2x + 5 < 7

-2 (1) + 5 < 7

-2 + 5 < 7

3 < 7
