One number is five less than a second number. Five times the first is 2 more than 2 times the second. Find the numbers.

Your numbers are 4 and 9

We’ll call the first number a, the second b.
a = b - 5
5a = 2b + 2
(if you’re not sure where I got those equations, just let me know in the comments.)

Then we’ll substitute the first value into the second equation:

5(b - 5) = 2b + 2
5b - 25 = 2b + 2
3b = 27
b = 9

a = b - 5
a = 9 - 5 = 4

What class is this? i have no idea and i'm not going to give you the wrong answer. do you have a graph that goes with all the questions
