\frac{3e^{t}}{4}y_{2}=38.6
The equation is in standard form.
\frac{4\times \frac{3e^{t}}{4}y_{2}}{3e^{t}}=\frac{4\times 38.6}{3e^{t}}
Divide both sides by 0.75e^{t}.
y_{2}=\frac{4\times 38.6}{3e^{t}}
Dividing by 0.75e^{t} undoes the multiplication by 0.75e^{t}.
y_{2}=\frac{772}{15e^{t}}
Divide 38.6 by 0.75e^{t}.
