18=(x+y)/3
18=(x-y)*3/5
==>(x+y)/3=(x-y)*3/5
==> 5(x+y)=9(x-y)
==>5x+5y=9x-9y
==>4x=14y
==>x=7/2y
18=(7/2y+y)/3
==>9/2*y=18*3
==>y=12
==> x=7/2*12=42

(y-k)²=4p(x-h)
p is distance from directix to vertex which is also the distance from vertex to focus
if it opens to the right, then p is positive
if it opens to the left, then p is negative
so we know that directix is-8 and focus is (8,0)
directix is behind the parabola
so therfor the parabola opens to the right
distance from x=-8 to (8,0) is 16 units
16/2=8
p=8
vertex is 8 units to right of directix or 8 units to the left of focus
(8,0) is focus so vertex is (0,0)
(h,k) is vertex
(y-k)²=4p(x-h)
(y-0)²=4(16)(x-0)
y²=64x

cos2x = (cosx)^2 - (sinx)^2;
tan2x = (sin2x)/(cos2x);
cosx = 5/13 from formula (sinx)^2 + (cosx)^2 = 1;
=> sin2x = 120/169;
