Answer:
No solution
Step-by-step explanation:
4x + y = -2
-20x - 5y = -3
<u><em>Using the Elimination method </em></u>
(4x + y = -2 ) 5
20x + 5y = -10
-20x - 5y = -10
0 = -10

81 inches x 1 foot
------------
12 inches
81/12 = 6.75 C
It is 12 it’s is 12 it has to be 12
<h3><u>-2 + 6 = 4</u></h3><h3><u>0 + 6 = 6</u></h3><h3><u>5 + 6 = 11</u></h3>
We can easily enumerate E and F:
The intersection 
is a set composed by all the element belonging to both E and F, i.e. 4.
The intersection of this set with D works in the same way, but it's actually a trivial one, since is a subset of D. In fact, D is the set of all integers, while 4 is a particular integer. And in general, if A is a subset of B, then the intersection between A and B is A itself, so the final answer is
