<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>

Answer:
#1: -1.5, -0.5, 1/2, 1.5
#2: -3, -1, 1.2, 2.3
Step-by-step explanation:
#1
First we have to figure out the correct order before we plot.
Find the biggest number:
looking at the number the biggest would be 1.5
Find the smallest number:
Looking at the number the smallest would be -1.5
Now that we have that we can easily figure out the rest...
(Going from least to greatest; like on a number line)
-1.5, -0.5, 1/2, 1.5 (That is how you will place the first one)
#2
(Use the steps from above to find the answer)
Biggest: 2.3
Smallest: -3
Order: -3, -1, 1.2, 2.3 (Placing on number line use that order)
Hope this helps :)
Answer:
