The graph shows a number line with an open circle at negative one and shading to the left.
The graph shows a number line with an open circle at negative six and shading to the right.
The graph shows a number line with an open circle at negative six and shaded to the left.

Answer 1

-1

Explanation:

-2x + 5 < 7 (subtract 5 from both sides)

-2x < 7-5

-2x < 2

x < 2/-2

x < -1

Answer 2

first option

Explanation:

solving the inequality

- 2x + 5 < 7 ( subtract 5 from both sides )

- 2x < 2

divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x > - 1

this means an open circle at negative one and shading to the right
