Ma=f
Swap sides so that all variable terms are on the left hand side.
aM=f
The equation is in standard form.
\frac{aM}{a}=\frac{f}{a}
Divide both sides by a.
M=\frac{f}{a}
Dividing by a undoes the multiplication by a.
Ma=f
Swap sides so that all variable terms are on the left hand side.
\frac{Ma}{M}=\frac{f}{M}
Divide both sides by M.
a=\frac{f}{M}
Dividing by M undoes the multiplication by M.
