I don’t get this at alllllll
zloy xaker [14]
Hey there!

We have to multiply, the "a" becomes a "negative a" ; solve this fraction to understand this step

Like: (multiplication)  -a = 1/8

Let's multiply by a negative one on each of your sides

     a = -(1/8) 
* 1. * 1
Solve this and that gives us our answer⬆️

We have "two solutions " in this problem, which 1/8 or -1/8

Answer: 1/8 or -1/8 (option A)

Good luck on your assignment and enjoy your day
