Use proof by contradiction to show that there exist no integers x x\,x and y y\,y for which 24x+16y=524x + 16y = 524x+16y=5.
Practise Edexcel A Level Maths Algebraic Methods with exam-style questions for A Level Maths. 100 questions covering 1.1 Proof by Contradiction, 1.2 Algebraic Fractions, 1.3 Partial Fractions, 1.4 Repeated Factors, and 1.5 Algebraic Division, matched to the Edexcel A Level Maths (9MA0) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
