Rearrange the following equation to find x in terms of a and b in simplest form (assume that a =/-3b)
the / should be through the = to show a is not equal to -3b
Couldnot find the key for it sorry!
this is where i get unsure.
I think then it becomes
which then becomes
which is x= a-b
Are my workings out right or am I completley of the mark?
Apologies for the way i may have presented my workings out still getting to grips with showing my workings out on a computer
