68 = 7b - 9 -7b = -68-9 b = (-68-9)/-7 = 11
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
The first 5 primes are 2, 3, 5, 7, 11 Their product = 2310. Average of 5 numbers is 55 so their sum is 55*5 = 275. Two numbers, 68 and 93 are added so the new sum of seven numbers is 275 + 68 + 93 = 436 So the new average is 436/7 = 62.3 (to 1 dp).
476/7 = 68
