Question $1-$ What did i do wrong and show step by step how to get to the answer. I am confused for statics

Knowing that $=33$ and $M_C=340ft*lb,$ reduce the force$-$couple system

shown to an equivalent force and couple at point B$.$ Enter the magnitude of the

couple at B below in $ft*lb$ to the nearest whole $ft*lb.$ Enter a positive number if

the couple at $B$ is CCW and a negative number if the couple at $B$ is $CW.$

Your written solution must show the magnitude and direction of the equivalent

force and the equivalent couple at B$.$ You should also calculate the equivalent

force and couple at point A and at point $C$ for practice.
