Twenty less than a number is more than twice the same number. Step by step to get the answer

N=number

N - 20 > 2N

-20 > N

Step 1: Set up an inequality based on the words. twenty less means minus twenty or - 20. I used N for the unknown number. twenty less than a number, means N - 20. Is more than means its greater so N - 20 > than the twice the same number which is 2N. so N-20>2N is my inequality

Step 2: subtract N from both sides and you are left with - 20 > N. which means that N has to be less than - 20. So, - 21, - 22, - 23 ... would all work.

20 less than (-20) a number (n) is more than (>) twice the same number (2n)

-20+n>2n

minus n both sides

-20>n

n<-20
