Question

If a number n is subtracted from 18, the result is four less than n. What is the value of n? (Write an equation first before solving.)

Answer 1

I think the equation will be written as 4(18-n)<n

Answer 2

no i don't think that is right

Answer 3

"n is subtracted from 18" : \(18-n\)
"four less than n": \(n-4\)
solve
\[18-n<n-4\]

Answer 4

sorry i meant solve
\[18-n=n-4\]

Answer 5

add \(n\) to both sides, get
\[18=2n+4\] then add 4 to both sides
\[22=2n\] divide both sides by 2 \[11=n\]

Answer 6

Yes you are correct!
