You have to bring the 3 over to the right hand side(rhs), then you will get 3/4x = 9+3 correct? then, remembering that you have to place variables at one side and numbers at the other side. so, 3/4x = 12, then, it becomes 1/4 = 4x . finally, you will get to this answer, 1/16 as the answer. good luck in algebra! algebra problems are interesting!
