Answer 1

Your equation is wrong ..
Let us suppose the no . Is x then
X/2 -19.7= - 4.1 then x becomes now
31.2
In question half of the no is subtracted....Again half of the no.....U miss the half word...

Answer 2

Answer:31.2

Step-by-step explanation:

Let the no . is x

so according to question

$\frac{x}{2}-19.7= -4.1\\\\\frac{x}{2}=15.6\\\\x=31.2$

so the number is 31.2
