X + 9 = 2x - 8
2x - x = 9 + 8
x = 17
BC = x = 17
answer
17 units
$200 x 12 = 2,400 (number of pencils they bought in 2006)
3/4 x 2,400 = 1,800 (number of pencils they used)
2,400 - 1,800 = 600 (number of pencils remaining)
1,800 - 600 = 1,200 (number of pencils needed)
They had to buy 1,200 more pencils in 2007.
<span>|7x-7|+3 = 4x+1 ⇒⇒⇒ add (-3) to both sides
</span>
<span>∴ |7x-7| = 4x - 2
</span>
According to the absolute rule
∴ 7x - 7 = 4x - 2 OR -(7x - 7) = 4x - 2
7x - 4x = 7 - 2 l 7x - 7 = -4x + 2
3x = 5 l 7x + 4x = 2 + 7
x = 5/3 l 11 x = 9 ⇒⇒⇒ x = 9/11
∴ x = 5/3 and 9/11
So, the correct answer is option <span>B. 5/3 and 9/11</span>
