If (a – b) is 7 more than (c + d) and (a + b) is 3 less than (c – d), then (a – c) is:	Choose the correct choice from the following options:	A) 6	B) 2	C) 3	D) 4	E) 5
(a – b) – (c + d) = 7 and (c – d) – (a + b) = 3   =&gt; (a – c) – (b + d) = 7 and (c – a) – (b + d) = 3   =&gt; (b + d) = (a – c) – 7 and (b + d) = (c – a) – 3   =&gt; (a – c) – 7 = (c – a) – 3 =&gt; 2(a – c) = 4 =&gt; (a – c) = 2   ANSWER:2
