Answer:
Step-by-step explanation:consecutive integers are represented by x, x+1 , so for this problem the greater one is represented by x + 1.
Now you need to translate the problem. the greater is seven less than 1/3 the smaller
---> x + 1 = (1/3)*x - 7 ---> now solve for x (the smaller) and x+1 (the greater)
***hint: to get rid of fractions in an equation you can always multiply EVERYTHING by the denominator , 3 in this case
