Question

Anima thinks of a number and subtract 5/2 from it. she multiplies the result by 8. the result now obtained is 3 times the same number she thought of. what is the number?​

Answer 1

Answer:

x=4

Step-by-step explanation:

let the no. be x

(x-5/2)×8=3x

(2x-5/2)×8=3x

16x-40/2=3x

16x-40=3x×2

16x-6x=6x

16x-6x=40

10x=40

x=4
