m=13,4A
Multiply 2 and 6,7 to get 13,4.
13,4A=m
Swap sides so that all variable terms are on the left hand side.
\frac{13,4A}{13,4}=\frac{m}{13,4}
Divide both sides of the equation by 13,4, which is the same as multiplying both sides by the reciprocal of the fraction.
A=\frac{m}{13,4}
Dividing by 13,4 undoes the multiplication by 13,4.
A=\frac{5m}{67}
Divide m by 13,4 by multiplying m by the reciprocal of 13,4.
m=13,4A
Multiply 2 and 6,7 to get 13,4.
