Question 84270
Let x=second number
2x=2 times the second number
2x+5=5 more than 2 times the second

Then 2x+5=the first number

Now we are told that:

2x+5-x=15  subtract 5 from both sides

2x+5-5-x=15-5  collect like terms

x=10  -------------------------------second number

2x+5=2*10+5=25 ---------------------first number

CK

25-10=15
15=15


Hope this helps ----ptaylor
