Question

I have 6 equations with 6 unknowns, I am having trouble getting the right solutions for Cx, Bx, Az, Bz, Ay, and Cy. here are my six equations, Sum of Forces in x direction = -Cx -Bx + 7 =0 ; Sum of Forces in y direction = -Ay -Cy -12 = 0; Sum of forces in z direction = Bz + Az - 5 = 0; Sum of Moments in x direction = Bz(0.4) - Cy(0.75) + Az - 5 =0; Sum of moments in y direction = -Cx(.75) + Az = 0; Sum of moments in z direction = -3 +Bz(0.4) + Ay - 7 = 0; From the answer in the back of the book i know that Cx = 41.6 and Bz = 92. Please solve for the 6 unknowns using the equations given and I can solve it from there.
