Answer 3

To solve this problem, we can use algebraic equations to represent the given information and then solve for the unknown number.

Let's denote the unknown number as "x". The problem states that "10 is added to three times a number", which can be represented as "3x + 10". The problem also states that "the result is 16 more than that number", which can be represented as "3x + 10 = x + 16".

Now, we can solve for the value of x by rearranging the equation and isolating the variable.

Equation Setup: 3x + 10 = x + 16

Solving for x: Subtract x from both sides: 3x - x + 10 = 16 2x + 10 = 16

Subtract 10 from both sides: 2x = 16 - 10 2x = 6

Divide by 2: x = 3

So, the unknown number is 3.

Therefore, the number we're looking for is 3.
