Hii....
Here is your answer
_______________________________________________________

Let, Amina think a number x

A. T. Q

8(x-5/2) = 3x

8x - 8×5/2 = 3x

8x - 4×5 = 3x

8x - 20 = 3x

8x - 3x = 20

5x = 20

x = 20/5

x = 4

Hence, the number is 4

Hope it helps you!!

Let the number she thought be x

ATQ ,she subtract the 5/2 from the no.= x-5/2

She multiply the result by 8 =8(x-5/2)

Solution:-

• 3x = 8(x-5/2)
• 3x=8x -20
• 20=5x
• x=4

So, the number she thought is 4.
