Is there a missing "than" in your equation? It makes more sense as "2x less than..."
"2 times the sum of 2x and 1 is equal to the sum of 2 and 5" is written in equation as: 2(2x+1)= 2+5
Then, depending on the language of the first portion, the complete equation is either "2(2x+1)-2x= 2+5 or 2x-2(2x+1)= 2+5" Either way, expand the multiplication, combine x terms, and collect them on one side of the equality and non-x terms on the other, then divide to find x.
