Solve for m:
(-3 m)/7 = 12

Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12

(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12

(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3

(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3

(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3

(-1)^2 = 1:
m = (-7×12)/3

12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28

Remember that a double angle formula for cosine is
$\cos(2x)=\cos^{2}x-\sin^{2}x$

So
$\cos^{2}(2x)-\sin^{2}(2x)=\cos(4x)$
$\rightarrow \cos^{2}(2x)-\sin^{2}(2x)=\cos(2*2x)$
$\rightarrow \cos^{2}(2x)-\sin^{2}(2x)=\cos^{2}(2x)-\sin^{2}(2x)$
