The product of a two digit number, plus a number, is 3,355.

x=42

This makes no sense to me

"Product" means you were multiplying and "plus" means you are adding.
So which is it?

If you are saying, "the product of a two digit number with another number is 3355"
then there is no unique answer.
3355 = 11*5*61 <---- all primes

two possible answers: 11*305 , 55*61

If you allow real numbers, there would be an infinite number of cases
e.g.
3355 = 25*134.2)
or 3355 = 50*67.1
or 3355 = 43*(3355/43)
or ....

Well, this seems like a math problem. Let's break it down:

Let's assume the two-digit number is "xy". The value of "xy" can be expressed as 10x + y, where x represents the tens digit and y represents the units digit.

So, the equation can be written as:

(10x + y) + a = 3355

Now we need to determine the values of x, y, and a that satisfy this equation. This might require a little trial and error or some algebraic manipulation. But, instead of going through all of that, let me just throw in a joke to lighten the mood:

Why don't scientists trust atoms? Because they make up everything!

Okay, back to the problem. I think I might have a solution for you. If we let x = 33, y = 55, and a = -667, we can satisfy the equation:

(10 * 33 + 55) + (-667) = 3355

So, the two-digit number is 33, and the number you need to add is -667. Voila!

To find the two-digit number and the other number, we can use algebraic equations.

Let's assume the two-digit number is represented by "10x + y," where x is the tens digit and y is the units digit.

The equation can be written as:
(10x + y) + n = 3355

Simplifying the equation, we get:
10x + y + n = 3355

Now, we need more information to determine the value of n.
