V_{s}P_{s}T_{m}=P_{m}V_{m}T_{s}
Multiply both sides of the equation by P_{s}T_{m}.
P_{m}V_{m}T_{s}=V_{s}P_{s}T_{m}
Swap sides so that all variable terms are on the left hand side.
T_{s}V_{m}P_{m}=P_{s}T_{m}V_{s}
The equation is in standard form.
\frac{T_{s}V_{m}P_{m}}{T_{s}V_{m}}=\frac{P_{s}T_{m}V_{s}}{T_{s}V_{m}}
Divide both sides by V_{m}T_{s}.
P_{m}=\frac{P_{s}T_{m}V_{s}}{T_{s}V_{m}}
Dividing by V_{m}T_{s} undoes the multiplication by V_{m}T_{s}.
V_{s}P_{s}T_{m}=P_{m}V_{m}T_{s}
Variable P_{s} cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by P_{s}T_{m}.
P_{s}T_{m}V_{s}=P_{m}T_{s}V_{m}
Reorder the terms.
T_{m}V_{s}P_{s}=P_{m}T_{s}V_{m}
The equation is in standard form.
\frac{T_{m}V_{s}P_{s}}{T_{m}V_{s}}=\frac{P_{m}T_{s}V_{m}}{T_{m}V_{s}}
Divide both sides by V_{s}T_{m}.
P_{s}=\frac{P_{m}T_{s}V_{m}}{T_{m}V_{s}}
Dividing by V_{s}T_{m} undoes the multiplication by V_{s}T_{m}.
P_{s}=\frac{P_{m}T_{s}V_{m}}{T_{m}V_{s}}\text{, }P_{s}\neq 0
Variable P_{s} cannot be equal to 0.
