Answer 2

Answer:

a=3

Step-by-step explanation:

3a-4=5

put the 4 on the same side as the 5 and switch it from - to +

Ex.  3a=5+4

now add the 5 and the 4

Ex.   3a=9

now isolate the variable (thats the letter) by dividing 3a by 3, then divide the 9 by 3 simultaneously

Ex.   3a/3=a  |  9/3=3

Then v

       a=3
