#10x+12#

Explanation:

For #3(4x+3)#, we distribute the parentheses/brackets with #x(y+z)=xy+xz#

Therefore, #3(4x+3)=3*4x+3*3# which is equal to #12x+9#.

Whole equation:
#12x+9-2x+3#

We group like terms:
#12x-2x+3+9#
We subtract:
#10x+3+9#
Then add:
#10x+12#

Therefore, #3(4x+3)-2x+3# expanded is equal to #10x+12#
