-2x + (1/2)y = 18

(1/2)y = 2x + 18

y/2 = 2x + 18

y = 2*(2x + 18)

y = 2*2x + 2*18

y = 4x + 36

The x intercept is the value of x, when the y value is 0.

0 = 4x + 36

0 - 4x = 36

-4x = 36

x = 36/-4

x = -9

The x intercept is -9

I hope this helps.

Tan + Cos / 1 + Sin = Sec

$\tan x+\frac{\cos x}{1+\sin x}\\\\ =\frac{\sin x}{\cos x}+\frac{\cos x}{1+\sin x}\\\\=\frac{\sin x(1+\sin x)+\cos^{2} x}{\cos x(1+\sin x)}\\\\=\frac{\sin^{2} x+\cos^{2} x+\sin x}{\cos x(1+\sin x)}\\\\=\frac{1+\sin x}{\cos x(1+\sin x)}\\\\=\frac{1}{\cos x}\\\\=\sec x$
