​

Answer 1

Answer:

answer is 4

Step-by-step explanation:

Lets assume the number to be x.

First, lets break the question step-by-step for easy understanding.

Step 1: 5/2 is subtracted from x.

Step 2: The answer in Step 1 is multiplied by 8.

Step 3: The answer derived in Step 2 is 3 times of x.

Hence, the equation could be formed as follows:

(x-5/2)*8=3x

(2x-5)*4=3x

8x-20=3x

8x-3x=20

5x=20

x=20/5

x=4

Therefore, the number is 4.
