Question

If a number n is subtracted from 18, the result is four less than n. What is the value of n?

Answer 1

So set up the equation

18 - n = n - 4

And solve for 'n'

Answer 2

This will be
=>18-n=n-4
=>2n=22
=>n=11

Answer 3

Do I Subtract 18 From Both Sides?

Answer 4

Always take all variables on one side & all constants on other side while solving such type of questions . (Here n is variable to be found out & the numbers are constants )

Answer 5

Right...so you would add 'n' to both sides

You'll then have

18 = 2n - 4

Then you want to isolate 2n...so add 4 to both sides

22 = 2n

And you want to solve for 'n' so divide both sides by 2

11 = n
