See the entire solution process below:

Explanation:

Step 1) Add color(red)(2)2 to each side of the equation to isolate the aa term while keeping the equation balanced:

a/5 - 2 + color(red)(2) = 9 + color(red)(2)a52+2=9+2

a/5 - 0 = 11a50=11

a/5 = 11a5=11

Step 2) Multiply each side of the equation by color(red)(5)5 to solve for aa while keeping the equation balanced:

color(red)(5) xx a/5 = color(red)(5) xx 115×a5=5×11

cancel(color(red)(5)) xx a/color(red)(cancel(color(black)(5))) = 55

a = 55
