Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
