Mathematics - Give me challenging Algebra practice questions from Paper 1 without the memo

Here are 5 practice questions. Question 1 — Solve for x: 2x/(x+2) = (x+3)/(x-1). Question 2 — If f(x) = x2 + 2x - 3, find and simplify f(2x+1). Question 3 — Solve the inequality x2 - 4x - 3 > 0. Question 4 — Given f(x) = (x-1)/(x+1), find f-1(x). Question 5 — Solve for x and y simultaneously: y = x2 - x - 6 and y = 2x - 2.
