Question

variable a is 4 more than variable b. variable a is also 1 less than b. which of the following pairs of equations best models the relationship between a and b? 1.a = b 4 a = b − 1 2.a = 4b a = b 1 3.b = a 4 b = a − 1 4.b = 4a b = a 1

Answer 1

a = b + 4 and a = b - 1...or b = a - 4 and b = a + 1
