x*-8 would be -8x
then you would divide -8 by both sides
should get a decimal as your answer I believe
So the equation is x + 2x + 5= 29
Here are the steps -5 -5
-----------------------
3x = 24
Divide both sides by 3 so you get
x = 8
Then look back at the question, the second number has to be twice that number plus 5
So the 1st number is 8 The second # is 2(8)+5= 21
