Simple. You can just use the basic but important concept of order of operations to simplify this expression.

Explanation:

#-1+10(7a+2)-4a#

Remember. You are simplifying, not solving it; so do not solve for #a#.

Do the multiplication first.

#=-1+70a+20-4a#

Now, add the terms together to form the final simplified version of the expression.

#=66a+19#
