Ok, I hope I do this right...
The problem says
Set up a system of lineral equations and solve for the indicated quantinties.
Two positive numbers have a difference of 8. The larger number is 2 less than 3 times the smaller number. Find the numbers.
I have tried to say... a+b=-8 and 3b-2a=8 and then solve for b so I can substitute it in the 2nd equation...
2nd equation would then be
3(-a-8) - 2a = 8
Then I solve for a. But I am doing something wrong because I get a= -6.4
The numbers are 13 and 5 but I can't come up with the right equations
