Answer 2

Step-by-step explanation:

Let the number thinked by Amina be x

According to the question she substracted the number by 5/2 and then multiplied it with 8

Equation formed

= 8×(x-5/2)

= 8x-20

then the result came is equal to three times the number

that means

= 3x

the equation formed

=> 8x-20 = 3x

=> 8x-3x = 20

=> 5x = 20

=> x = 20/5

=> x = 4

Therefore, the number or x is equal to 4.
