The larger of two consecutive integers is 7 greater than twice the smaller. Find the integers.


A) 4,5
B) -8,-9
C) -5,-6

  • Algebra 1 -

    integer 1 = a
    integer 2 = b

    b-a = 1 (b is one more than a)
    b-7 = 2*a (b is seven more than two times a)

    a = b-1
    b-7 = 2*(b-1)
    b-7 = 2b-2
    b = -5

    so a should be -6

    answer is C)
