Problema Solution
One thirdof the sum of two concecutive integers is 5 less than the smaller integer. What is the larger integer.
Answer provided by our tutors
let x and y be the two consecutive numbers and y>x
since the numbers are consecutive we can write
y = x + 1
One third of the sum of two concecutive integers is 5 less than the smaller integer
(1/3)(x + y) = x - 5
plug y = x + 1 into the previous equation
(1/3)(x + x + 1) = x - 5
by solving the equation we find
x = 16
click here to see the step by step solution of the equation
y = x + 1 = 16 + 1 = 17
the numbers are 16 and 17.
