Hi Jose,
Here's a similar problem to the one you posted.
Three times a number, added to 5, is 29. Find the number.
Let n = a number. Then 3 x n, or 3n is three times a number.
3n + 5 is three times a number added to 5.
3n + 5 = 29 is three times a number, added to five, is 29.
Now you have an equation, and you can solve for the number, n.
3n + 5 = 29 Start by subtracting 5 from both sides.
-5 = -5
So now you have
3n = 24
To solve for n (get n by itself), divide both sides by 3.
3n/3 = n
24/3 = 8
n = 8
