Question 81737
Let x=first number
then 3x-1=second number

Now we are told that:

(3x-1)-x=47 get rid of parens

3x-1-x=47  add 1 to both sides

3x-1+1-x=47+1  collect like terms

2x=48  divide both sides by 2

x=24  -------------------------------the first number

3x-1=3(24)-1=72-1=71----------------------------second number

CK

71-24=47
47=47
