Question

LITERAL EQUATIONS K= AP/2 SOLVE FOR A

Answer 1

Step One: Undo the division of AP by 2 by multiplying both sides by 2 (results in 2K=AP)

Step Two: Isolate A by dividing AP by P, and 2K by P as well (results in (2K)/P=A)

Final Answer: A=(2K)/P

Answer 2

Watch closely.  I'll try to go slow.
Stop me if I go too fast, or if I do anything you don't understand.

Ready ?

You said                                     K        = A P / 2

Multiply each side by  2 :      2 K        = A P

Divide each side by ' P ' :    2 K / P  =  A

OK ?
