1.	Find a solution to the equation using backtracking.
		A.	a = 5	B.	a = –2
		C.	a = 2	D.	a = 3
		Hint
	2.	Find a solution to the equation using backtracking.
		A.	n = –89	B.	n = –100
		C.	n = –12	D.	n = 10
		Hint
	3.	Find a solution to the equation using backtracking.
		A.	c = 8	B.	c = –1
		C.	c = 2	D.	c = –14
		Hint
	4.	Find a solution to the equation by doing the same thing to both sides. 8p + 14 = 2p – 22
		A.	p = –1	B.	p = 6
		C.	p = 1	D.	p = –6
		Hint
	5.	Find a solution to the equation by doing the same thing to both sides. 3(5f + 7) + 9(f + 4) = 9
		A.	f = –9	B.	f = –2
		C.	f = –10	D.	f = –12
		Hint
