HA=\frac{9BH}{16}
The equation is in standard form.
\frac{HA}{H}=\frac{9BH}{16H}
Divide both sides by H.
A=\frac{9BH}{16H}
Dividing by H undoes the multiplication by H.
A=\frac{9B}{16}
Divide \frac{9HB}{16} by H.
\frac{9}{16}HB=AH
Swap sides so that all variable terms are on the left hand side.
\frac{9H}{16}B=AH
The equation is in standard form.
\frac{16\times \frac{9H}{16}B}{9H}=\frac{16AH}{9H}
Divide both sides by \frac{9}{16}H.
B=\frac{16AH}{9H}
Dividing by \frac{9}{16}H undoes the multiplication by \frac{9}{16}H.
B=\frac{16A}{9}
Divide AH by \frac{9}{16}H.
