why are you repeating numbers ??
assuming this is "One positive integer is 3 less than twice another. The sum of their squares is 170"
x = 2y – 3
x² + y² = 170
(2y – 3)² + y² = 170
4y² + 9 – 12y + y² = 170
5y² – 12y – 161 = 0
solving, we get y = 7 or –23/5
skipping the second result
y = 7
x = 2y – 3 = 2•7 – 3 = 11
check
7² + 11² = 170
49 + 121 = 170 ok

n = one integer
2n  33 = 2nd integer
=========================
n^2 + (2n  33)^2 = 170,170
n^2 + 4n^2  264n + 1089 = 170,170
5n^2  264n  169081 = 0
n^2  52.8n = 33816.2 .... complete the square (52.8 / 2)^2 = 696.96
n^2  52.8n + 696.96 = 33816.2 + 696.96 = 34513.16
(n  26.4)^2 = +/ 185.7771784
n = 212.1771784 <<< not an integer,
something is wrong with this question ... As it is worded it is impossible. I believe you nade ab error entering the question. Try again.
