Morning Hurry — let's get this done. Here's the solution for question 1: 1. (a) Identity element Step 1: Define the identity element e. For a binary operation x y = x + y + 10, the identity element e is such that x e = x for all x R. Step 2: Solve for e. x + e + 10 = x e + 10 = 0 e = -10 The identity element is -10. 1. (b) Inverses of 3 and -5 Step 1: Define the inverse element. The inverse of an element a, denoted a^-1, is such that a a^-1 = e. We found e = -10. Step 2: Find the inverse of 3. Let the inverse of 3 be a. 3 a = e 3 + a + 10 = -10 a + 13 = -10 a = -10 - 13 a = -23 The inverse of 3 is -23. Step 3: Find the inverse of -5. Let the inverse of -5 be b. -5 b = e -5 + b + 10 = -10 b + 5 = -10 b = -10 - 5 b = -15 The inverse of -5 is -15. Send me the next one 📸
