Answer 2

Answer:

18

Step-by-step explanation:    

To find the number, write an algebraic equation with the given information. Let the variable n represent the unknown number.

Now, break it by parts - "three times a number" would be $3n$. The "is" means that it equals something, giving us $3n =$. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is: $5n -36$. So, put it all together and it is $3n = 5n-36$.

Next, solve the equation for n. The answer will be the number.

$3n = 5n-36\\0 = 2n - 36\\36 = 2n \\n = 18$

Thus, the number is 18.
