I believe it’s A sorry if it’s incorrect
We want to get b alone so I would start by multiplying 2 to get it on the other side of the = sign. So then I have 2L=a-b. I would subtract a on both sides and then I would have 2L-a= -b. We don't want a -b so I would multiply everything by -1 so then the answer would then be a positive b= -2L+a
The answer would be 7/3. You would divide them both by 3. You just divide them by the same number to the point were you cant divide both by the same number anymore. For example 18/9 you can divide it by 2 to get 2.
1024 is the answer to this problem.
