\left(35P-H_{B}\right)\times 2-3H_{B}=0
Multiply both sides of the equation by 3.
70P-2H_{B}-3H_{B}=0
Use the distributive property to multiply 35P-H_{B} by 2.
70P-5H_{B}=0
Combine -2H_{B} and -3H_{B} to get -5H_{B}.
-5H_{B}=-70P
Subtract 70P from both sides. Anything subtracted from zero gives its negation.
\frac{-5H_{B}}{-5}=-\frac{70P}{-5}
Divide both sides by -5.
H_{B}=-\frac{70P}{-5}
Dividing by -5 undoes the multiplication by -5.
H_{B}=14P
Divide -70P by -5.
\left(35P-H_{B}\right)\times 2-3H_{B}=0
Multiply both sides of the equation by 3.
70P-2H_{B}-3H_{B}=0
Use the distributive property to multiply 35P-H_{B} by 2.
70P-5H_{B}=0
Combine -2H_{B} and -3H_{B} to get -5H_{B}.
70P=5H_{B}
Add 5H_{B} to both sides. Anything plus zero gives itself.
\frac{70P}{70}=\frac{5H_{B}}{70}
Divide both sides by 70.
P=\frac{5H_{B}}{70}
Dividing by 70 undoes the multiplication by 70.
P=\frac{H_{B}}{14}
Divide 5H_{B} by 70.
