ab+c=bc-a

make a the subject form

can anyone help with this.

Firstly, get all the 'a's on one side. To do this, add 'a' to both sides



Now, remove the 'c' from the left side. To do this, subtract c on both sides.





Factorise a on the left.



Divide both sides by (b+1);





I hope it helped! :)
