please help me ​

Answer 1

Here is the answer for your question..

Answer 2

Okay so let the number Amina thought be "x"

She subtracted 5/2 from x

x - 5/2

Then she multiplies the result by 8

(x - 5/2) * 8

The result now obtained is 3 times the same number she thought​

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

Now we need to solve this linear equation to find x

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

(Taking the brackets out)

8x - 20 = 3x

8x - 3x - 20 = 0

5x = 20

x = 4

Amina thought of the number 4.

Hope this helps! :p
