Answer:
2 or -2
Step-by-step explanation:
|3x|=6
Solve Absolute Value.
|3x|=6
We know either3x=6or3x=−6
3x=6 (Possibility 1)
3x
3
=
6
3
(Divide both sides by 3)
x=2
3x=−6 (Possibility 2)
3x
3
=
−6
3
(Divide both sides by 3)
x=−2
Answer:
x=2 or x=−2
Let x represent the price they charge hardcover book and let y represent the price they charge for a paperback book.
4x + 10y = 62 . . . . . (1)
5x + 7y = 61 . . . . . . (2)
(1) x 5 ⇒ 20x + 50y = 310 . . . . (3)
(2) x 4 ⇒ 20x + 28y = 244 . . . . (4)
(3) - (4) ⇒ 22y = 66
y = 66 / 22 = 3
4x + 10(3) = 62
4x = 62 - 30 = 32
x = 32 / 4 = 8
Therefore, the price for a hardcover book is $8 and the price for a paperback book is $3.
