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
. The "is" means that it equals something, giving us
. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is:
. So, put it all together and it is
.
Next, solve the equation for n. The answer will be the number.

Thus, the number is 18.
