\left(35P-HI_{B}\right)\times 2-3H_{B}=0
Multiply both sides of the equation by 3.
70P-2HI_{B}-3H_{B}=0
Use the distributive property to multiply 35P-HI_{B} by 2.
-2HI_{B}-3H_{B}=-70P
Subtract 70P from both sides. Anything subtracted from zero gives its negation.
-2HI_{B}=-70P+3H_{B}
Add 3H_{B} to both sides.
\left(-2I_{B}\right)H=3H_{B}-70P
The equation is in standard form.
\frac{\left(-2I_{B}\right)H}{-2I_{B}}=\frac{3H_{B}-70P}{-2I_{B}}
Divide both sides by -2I_{B}.
H=\frac{3H_{B}-70P}{-2I_{B}}
Dividing by -2I_{B} undoes the multiplication by -2I_{B}.
H=-\frac{3H_{B}-70P}{2I_{B}}
Divide -70P+3H_{B} by -2I_{B}.
\left(35P-HI_{B}\right)\times 2-3H_{B}=0
Multiply both sides of the equation by 3.

Multiply both sides of the equation by 3.
70P-2HI_{B}-3H_{B}=0
Use the distributive property to multiply 35P-HI_{B} by 2.
-2HI_{B}-3H_{B}=-70P
Subtract 70P from both sides. Anything subtracted from zero gives its negation.
-3H_{B}=-70P+2HI_{B}
Add 2HI_{B} to both sides.
-3H_{B}=2HI_{B}-70P
The equation is in standard form.
\frac{-3H_{B}}{-3}=\frac{2HI_{B}-70P}{-3}
Divide both sides by -3.
H_{B}=\frac{2HI_{B}-70P}{-3}
Dividing by -3 undoes the multiplication by -3.
H_{B}=\frac{70P-2HI_{B}}{3}
