cot^2 - tan^2 cos^2/sin^2 - sin^2/cos^2 (1 - sin^2)/sin^2 - (1-cos^2)/cos^2 1/sin^2 - 1 - 1/cos^2 + 1 1/sin^2 - 1/cos^2

x - y = 12, 2x/5 = y/3 + 6, Multiply both sides by 15, the common denominator: 6x = 5y + 90, 6x - 5y = 90, Multiply both sides of 1st Eq by -6 and add the 2 Eqs: x - y = 12 6x - 5y = 90 -6x + 6y = -72 6x - 5y = 90 y = 18, Substitute 18 for y in the 1st Eq: x - 18 = 12, x = 30...
