Question

If 1 is added to a number and the sum is tripled, the result is 19 more than the numbe. Find the number.

Answer 1

Hi Jeremiah,

 

Let's say x is our number. From the given information:

 

(x + 1) * 3 = x + 19

 

Now we can just solve for the number.

 

3 * x + 3 = x + 19   Subtract x and 3 from both sides.

 

2 * x = 16   Divide both sides by 2.

 

x = 8

 

You can just check this by plugging it back into our equation or by performing the calculations while reading the word problem.

 

Hope this helps!
