Answer:

Standard form is Ax + By = C where A is a positive integer

3x+1 = 2y

-2y -2y

3x-2y +1 =0

-1 -1

3x - 2y = -1

Answer:

3x - 2y = - 1

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Rearrange 3x + 1 = 2y into this form

Subtract 1 from both sides

3x = 2y - 1 ( subtract 2y from both sides )

3x - 2y = - 1 ← in standard form

Check the picture below.

thus then

$\bf \begin{cases}
y=100-a\\
y=a\sqrt{3}
\end{cases}\implies 100-a=a\sqrt{3}\implies 100=a+a\sqrt{3}
\\\\\\
100=a(1+\sqrt{3})\implies \boxed{\cfrac{100}{1+\sqrt{3}}=a}
\\\\\\
\textit{what is the altitude \underline{y} then?}\qquad y=100-a
\\\\\\
y=100-\cfrac{100}{1+\sqrt{3}}\implies y\approx 63.39745962156~yards$
