Question

​

Answer 1

Answer:

your answer is 5

explanation below

Step-by-step explanation:

Let’s call the unknown number ‘x’ for now.

A number (x) is multiplied by 3 (3x), and then 5 is added to it (3x + 5) to get 20 (3x + 5 = 20).

Now we have our equation 3x + 5 = 20. Let’s begin solving.

Step 1: Subtract 5 from both sides.

3x + 5 - 5 = 20 - 5:

3x = 15

Step 2: Divide both sides by 3.

(3x)/3 = 15/3

x = 5

Your ‘ number’ has been found. It is 5
