-300-0.4Ay=0
Multiply -0.6 and 500 to get -300.
-0.4Ay=300
Add 300 to both sides. Anything plus zero gives itself.
\left(-\frac{2y}{5}\right)A=300
The equation is in standard form.
\frac{\left(-\frac{2y}{5}\right)A}{-\frac{2y}{5}}=\frac{300}{-\frac{2y}{5}}
Divide both sides by -0.4y.
A=\frac{300}{-\frac{2y}{5}}
Dividing by -0.4y undoes the multiplication by -0.4y.
A=-\frac{750}{y}
Divide 300 by -0.4y.
-300-0.4Ay=0
Multiply -0.6 and 500 to get -300.
-0.4Ay=300
Add 300 to both sides. Anything plus zero gives itself.
\left(-\frac{2A}{5}\right)y=300
The equation is in standard form.
\frac{\left(-\frac{2A}{5}\right)y}{-\frac{2A}{5}}=\frac{300}{-\frac{2A}{5}}
Divide both sides by -0.4A.
y=\frac{300}{-\frac{2A}{5}}
Dividing by -0.4A undoes the multiplication by -0.4A.
y=-\frac{750}{A}
Divide 300 by -0.4A.
