8n-4=7.................................................
Answer:
Step-by-step explanation:
Let the number be x
x - 10

Do the multiplication both sides,

Arrange the terms to LHS according to their variables,

Factorise this polynomial

So what we notice here is when you're multiplying two numbers you're getting 0 as answer.
So one of them must be 0.
If (x-1) is 0
then x = 1
similarly,
x-6=0
then, x= 6.
So the possible values of x are 1 and 6.
