Answer:
<em>x = 2</em>
<em>divide each term by 3 and simplify.</em>
7 days between them. 27, 28, 29 , 30 , 1, 2, 3
3a + 6b = 45
2a - 2b = -12....multiply by 3
----------------
3a + 6b = 45
6a - 6b = - 36 ...(result of multiplying by 3)
---------------add
9a = 9
a = 1
3a + 6b = 45
3(1) + 6b = 45
3 + 6b = 45
6b = 45 - 3
6b = 42
b = 7
solution is : (1,7)
