Choose the set of equations that best represent the following information: The sum of two numbers, a and b, is 12. The first number, a, is 8 more than the second number. ab = 12, a 8 > b a b = 12, a = b 8 a a = 12, b - 8 = a a b = 8, a > b 12
The sum of two numbers, a and b, is 12. The first number, a, is 8 more than the second number. a + b = 12 ; a = 8 + b ; 8 + b + b = 12 ; 2b = 12 - 8 ; 2b = 4 ; b = 4/2 =2 ; b =2 ; a = 8 + 2 = 10 ; a + b =12 ; 10 + 2 = 12 ; 12 = 12
