Well let's start with the middle of this word problem which is 'a number' and call that X.
Then working outside this we see we want twice that number and that it will equal 85 so we have 2X = 85.
But we want 3 more than twice so let's add 3, we have 2X + 3 = 85
Finally we see we want a product of 5 and what is in the rest of the sentence so 5 times everything else before the equal sign, so that leaves us with 5 (2X + 3) = 85

Finally we see we want a product of 5 and what is in the rest of the sentence so 5 times everything else before the equal sign, so that leaves us with 5 (2X + 3) = 85
Solving for X
10X + 15 = 85
10X + 15 = 85
10X + 15 = 85 10X = 70
10X + 15 = 85 10X = 70X = 7
All the best
