assistant
How old was Jerry 5 years ago? ** We know that Jerry's Age/2 = Jerry's Age - 5
How old will Jerry be in 3 years? ** Therefore Jerry's Age = 2 Jerry's age - 10
How old will Jerry be in 3 years? ** Therefore -Jerry's Age = - 10
How old will Jerry be in 3 years? ** Therefore Jerry's Age = <<10=10>>10
How old will Jerry be in 3 years? ** In three years Jerry will be 13 because 10 + 3 = <<10+3=13>>13
