%Define matrices A, x, and b. Note that my x=[Bx,By,T] and I chose to draw Bx and By up and to the right, respectively, on my FBD at pin B.
A=[1,0,-sin(30*pi/180);0,1,cos(30*pi/180);0,0,-14*cos(30*pi/180)]
b=[600*sin(30*pi/180);600*cos(30*pi/180);-600*9*cos(30*pi/180)]
x=A\b
%Note that in my solution, x(1)=Bx, x(2)=By and x(3)=T. The units are lbs.
