Call the numbers s for the smaller number and l for the larger. From the problem statement, s + l = 35 and l = 2s + 7. From the first of these equations, s = 35 - l. Substituting this expression into the second equation yields:
l = 2(35 - l) + 7. Multiplying out yields:
l = 70 - 2l + 7. Adding like terms after collecting the terms with "l" on the left yields:
3l = 77 or l = 77/3. Then from the first equation s = 35 - 77/3 = 28/3
