2a=107.2-6c
Subtract 6c from both sides.
\frac{2a}{2}=\frac{107.2-6c}{2}
Divide both sides by 2.
a=\frac{107.2-6c}{2}
Dividing by 2 undoes the multiplication by 2.
a=\frac{268}{5}-3c
Divide 107.2-6c by 2.
6c=107.2-2a
Subtract 2a from both sides.
\frac{6c}{6}=\frac{107.2-2a}{6}
Divide both sides by 6.
c=\frac{107.2-2a}{6}
Dividing by 6 undoes the multiplication by 6.
c=-\frac{a}{3}+\frac{268}{15}
Divide 107.2-2a by 6.
