Asa and there is 2 attachments btw pppllzzz explain both of them

First problem.

3a - 4 <= 5

Add 4 to both sides.

3a <= 9

Divide both sides by 3.

3a/3 <= 9/3

a <= 3

Second problem.

n/(-3) + 5 > 4

Subtract 5 from both sides

n/(-3) > -1

Multiply both sides by -3.
When you multiply or divide both sides of an inequality by a negative number, the inequality sign switches direction.

n/(-3) * (-3) < -1 * (-3)

n < 3
