375J=6kyv^{2}
Multiply \frac{1}{2} and 12 to get 6.
6kyv^{2}=375J
Swap sides so that all variable terms are on the left hand side.
6yv^{2}k=375J
The equation is in standard form.
\frac{6yv^{2}k}{6yv^{2}}=\frac{375J}{6yv^{2}}
Divide both sides by 6yv^{2}.
k=\frac{375J}{6yv^{2}}
Dividing by 6yv^{2} undoes the multiplication by 6yv^{2}.
k=\frac{125J}{2yv^{2}}
Divide 375J by 6yv^{2}.
375J=6kyv^{2}
Multiply \frac{1}{2} and 12 to get 6.
\frac{375J}{375}=\frac{6kyv^{2}}{375}
Divide both sides by 375.
J=\frac{6kyv^{2}}{375}
Dividing by 375 undoes the multiplication by 375.
J=\frac{2kyv^{2}}{125}
Divide 6kyv^{2} by 375.
375J=6kyv^{2}
Multiply \frac{1}{2} and 12 to get 6.
6kyv^{2}=375J
Swap sides so that all variable terms are on the left hand side.
6yv^{2}k=375J
The equation is in standard form.
\frac{6yv^{2}k}{6yv^{2}}=\frac{375J}{6yv^{2}}
Divide both sides by 6yv^{2}.
k=\frac{375J}{6yv^{2}}
Dividing by 6yv^{2} undoes the multiplication by 6yv^{2}.
k=\frac{125J}{2yv^{2}}
Divide 375J by 6yv^{2}.
