Answer:

#3/10(a-10)+(3/4a-6)2 = color(green)(9/5a-15)#

Explanation:

I've made some assumptions (as noted by others).

#color(red)(3/10(a-10))+color(blue)((3/4a-6)2#

#color(white)("XXX")=color(red)((3a-30)/10)+color(blue)((3a-24)/(cancel(4)_2)cancel2)#

#color(white)("XXX")=color(red)((3a-30)/10) +color(blue)((15a-120)/10)#

#color(white)("XXX")=(18a-150)/10#

#color(white)("XXX")=9/5a-15#
