7(2n-2) = (3n+2)+3 simplify
14n-14 = 3n +5 bring like terms together
14n - 3n = 5+14 simplify
11n = 19 get n by itself
n = 19/11

7(2n - 2) = (3n + 2) + 3
14n - 14 = 3n + 2 + 3
11n = 19
n = 19/11
Answer: n = 19/11 or 1 8/11
Proof:
7(2[19/11]] - 2) = (3[19/11] + 2) + 3
7(38/11 - 2) = 57/11 + 2 + 3
266/11 - 14 = 57/11 + 5
24 2/11 - 14 = 5 2/11 + 5
10 2/11 = 10 2/11

7(2n-2)=(3n+2) +3
14n-14=3n+2 +3
14n -14=3n+5
14n=3n+19
11n=19
n=19/11 or 1 8/11
