What is your equation?

Is it:

\begin{cases}

bP = 1.0 \\

1.0 = 1.48A + (0.72 * (1-A))

\end{cases}

Or is it:

\begin{cases}

bP = 1, \\

0 = 1.48A + (0.72 * (1-A))

\end{cases}

Assuming that your equation is [tex]1.48A+ (0.72(1- A))= 0[/tex], first expand the multiplication: [tex]0.72(1- A)= 0.72- 0.72A[/tex].

That makes the equation [tex]1.48A+ 0.72- 0.72A= 0[/tex].

Now, combine the two "A" terms: 1.48A- 0.72A= (1.48- 0.72)A= 0.76A.

That makes the equation [tex]0.76A+ 0.72= 0[/tex].

Subtract 0.72 from both sides: [tex]0.76A= -0.72[/tex].

Finally, divide both sides by 0.76: [tex]A= -\frac{0.72}{0.76}= 0.9473[/tex]...

That makes the equation [tex]1.48A+ 0.72- 0.72A= 0[/tex].

Now, combine the two "A" terms: 1.48A- 0.72A= (1.48- 0.72)A= 0.76A.

That makes the equation [tex]0.76A+ 0.72= 0[/tex].

Subtract 0.72 from both sides: [tex]0.76A= -0.72[/tex].

Finally, divide both sides by 0.76: [tex]A= -\frac{0.72}{0.76}= 0.9473[/tex]...
