Find the numbers.
Having difficulty please help

That's easier if you look at it that way round. Say x= the first number and y=second number. Then your questions says that

x - y = 3
x^2 + y^2 = 89

Just solve the equations, and say what the first and second number are, not only
x= 'the answer' and y = 'the answer', K? Post your answer, we'll see if you're OK.
