P=s%5B1%5D%2Bs%5B2%5D%2Bs%5B3%5D Start with the given equation.


P-s%5B1%5D=s%5B2%5D%2Bs%5B3%5D Subtract s%5B1%5D from both sides.


-s%5B1%5D=s%5B2%5D%2Bs%5B3%5D-P Subtract P from both sides.


s%5B1%5D=-s%5B2%5D-s%5B3%5D%2BP Multiply EVERY term by -1 to make s%5B1%5D positive


s%5B1%5D=P-s%5B2%5D-s%5B3%5D Rearrange the terms.


-----------------------------------
Answer:


So the solution is s%5B1%5D=P-s%5B2%5D-s%5B3%5D
