Question 274758
{{{P = 5.1S - 1.2}}}
Whatever I do to 1 side of this equation, I 
have to do to the other side. Think of the
= sign as a balance point.
1st, I want to add {{{1.2}}} to both sides
{{{P = 5.1S - 1.2}}
{{{1.2 = 1.2}}}
Adding, I get
{{{P + 1.2 = 5.1S - 1.2 + 1.2}}}
which is the same as
{{{P + 1.2 = 5.1S}}}
Now I want to divide both sides by {{{5.1}}}
{{{(P + 1.2)/5.1 = (5.1/5.1)*S}}}
which is the same as
{{{(P + 1.2)/5.1 = S}}}
This is the answer. I can turn it around, and it doesn't change:
{{{S = (P + 1.2)/5.1}}}
