Answer :

Phionex
A = 115 + 1/2(p + s)
2(A - 115) = p + s
2(A - 115) - p = s

A = 115 + 1/2 (p + s)

you subtract 115 from both sides, and you get

A - 115 = 1/2 (p + s) 

now you multiply by 2 on both sides, and you get

(A - 115) * 2 = p + s            NOTE: I DISTRIBUTED 2 IN THE FOLLOWING EQUATION

now you subtract p on both sides to get s by itself and you get

2A - 230 - p = s

so the final answer is .......

[tex]s=2A-230-p[/tex]
