Question 1024559: How to solve this one? I'm confuse which one is the first and second number? Thank you.
One number is 5 more than another number. If you add 9 to 2 times the first number, the result is 3 times the second number.

You have to label them yourself.
Call x the first one and y the second one.
Then we can write
x = y + 5 and
9 + 2x = 3y
Now substitute in for x and get
9 + 2(y+5) = 3y
9 + 2y + 10 = 3y
19 + 2y = 3y
y = 19
and then
x = 24
How's that?
