I hope this helps you! :)
Use the following identity:
cos(2x)=1-2sin^2(x)
Simplify. Distribute 2 to all terms within the parenthesis
2(m -3) = 2m - 6
Simplify. Combine like terms
2m - 6 + 7 < 21
2m + 1 < 21
Isolate the m. Subtract 1 from both sides
2m + 1 (-1) < 21 (-1)
2m < 20
Isolate the m. Divide 2 from both sides
2m/2 < 20/2
m < 20/2
m < 10
m < 10 is your answer
