The answer is #-5a+14.2#, or #14.2-5a#.

Explanation:

#8+4a+6.2-9a#

Gather like terms.

#4a-9a+8+6.2#

Simplify.

#-5a+14.2# #larr# #color(red)("Try this instead")#.

This can also be written as:

#14.2-5a# #larr# This means the same as #-5a+14.2#, but maybe the computer program wants it the other way. If it's still incorrect, contact your teacher.
