A calculator is broken so that the only keys that still work are the sin, cos, tan, cot, sin^-1, cos^-1, and tan^-1 buttons. The display initially shows 0. In this problem, we will prove that given any positive rational number q, show that pressing some finite sequence of butt...

Substution Soluton MATH
1. subtituting we get -5x + 2 = 3x-14 so we get 8x = 16 and x=2, then plugging back in we get y = 2*-5 + 2 = -8 2. subtracting first from second equation gives us 4x = 4 so x = 1, and y = -1 3. 4x + 2 = 8 so 4x = 6, and x = 3/2 also thus 3/2*6 + 2y = 4 2y= -5 y = -5/2 maybe yo...
