#make x the subject of each of the formulae

What are the steps on answering it
How do I know what to do
Help would be greatly appreciated
multiply by x-a
so you’d have b(x-a)=x+a
expand the brackets bx-ab=x+a
minus the x so they’re both on the same side: bx-ab-x=a
add ba to other side so:
bx-x=a+ab
factorise by x so: x(b-1)=a+ab
multiply by the bracket so:
x=a+ab/b-1
