Question 74819
Let x=first number
Then (5x-5)=second number

Now we are told that the difference between these two numbers is 91.  So:

(5x-5)-x=91  get rid of parens

5x-5-x=91  add 5 to both sides

5x-5+5-x=91+5  collect like terms

4x=96  divide both sides by 4
x=24-------------------------------------first number

5x-5=5(24)-5=120-5=115---------------------------second number

ck

115-24=91
91=91
and
five less than 5 times the first=115
