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.
