(Please help ASAP 16 points! Thanks in advance!) solve -2a - 5 > 3
Bas_tet [7]

Answer:

a<-4

Step-by-step explanation:

To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.
