I am thinking of whole numbers. when I add them, their sum is 123. When I subtract the three lesser number from greater number, their difference is 45?
what are my numbers?
i am having trouble going step by step with this.
i added 61+62=123. i think this is wrong
please help me

I think you have a typo
If by "When I subtract the three lesser number from greater number" you meant
"When I subtract the lesser number from greater number" then the question is easy
x + y = 123
x - y = 45
2x = 168
x = 84
sub that back in the first equation,
y = 39
the two numbers are 84 and 39
check: 84+39 = 123
84-39 = 45
