Question

If 1 is subtracted from a number and the difference is multiplied by half the result is 7

Answer 1

let the number be x

so,if 1 is subtracted from the number then the difference would be: x-1

since it is multiplied by half the result, the equation is:

x-1  (x-1)/2 =7

(x-1)^2=14

taking square root on both sides,

x-1=3.74

so, x=4.74
