Question

Akashdeep thinks of a number and subtracts 7/2 from it . He multiplies the result by 4 to obtain a number which is 6 less than three times the number he had thought of . Find the number he had thought of .

Answer : 8

Answer 1

let the no. be x
therefore
4 (x - 7/2) = 3x - 6
4x - 14 = 3x - 6
4x - 3x = 14 - 6
x = 8

therefore he thought of 8

Answer 2

Let the number be $x$

Then,

⇒$4(x- \frac{7}{2} )=3x-6$

⇒$4(\frac{2x-7}{2})=3x-6$

⇒$2(2x-7)=3x-6$

⇒$4x-14=3x-6$

⇒$4x-3x=-6+14$

⇒$x=8$
