A rectangular plate is acted upon by the force and couple shown. This system is to be replaced with a single equivalent force. The force acting at point $B$ is $F_B=44N.$

Determine the value of $$ if the line of action of the equivalent force is to intersect line $CD300mm$ to the right of $D.($Include a minus sign if necessary.$)$

The value of $$ is
