7b + 3 - 4b = 3 - 3(b + 4)
3b + 3 = 3 - 3b - 12
3b + 3b = 3 - 12 - 3 = -12
6b = -12
b = -12/6 = -2
b = -2

Answer:
True
Step-by-step explanation:
Let A denotes the point (1,7)
Let B denotes the point (5,5)
We are supposed to find The length of the line segment containing the points
Formula : 

So,The length of the line segment containing the points (1,7) and (5,5) is 4.47 units is true.
Hence Option A is true
5/3+3x+4= 8
= 3x= 4-5/3
= 3x= 7/3
= x= 7/9
