1.	Find a solution to the equation using backtracking.
		A.	a = 5	B.	a = 3
		C.	a = 2	D.	a = –2
		Hint
	2.	Find a solution to the equation using backtracking.
		A.	n = 10	B.	n = –100
		C.	n = –89	D.	n = –12
		Hint
	3.	Find a solution to the equation by doing the same thing to both sides. 3 – 6m = 5 – 7m
		A.	m = 2	B.	m = –2
		C.	m = –5	D.	m = 0
		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 = 1
		C.	p = 6	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 = –12	B.	f = –2
		C.	f = –10	D.	f = –9
		Hint
