I'm new too, but I'm pretty sure if you have a question then you ask it, attach a picture if needed, and people might see it and answer.
Answer:
1) take the first part of the equation and work it by multiplying (x+2) by 3
3(x+2)+x
3x +6+x
2)put the answer you got into the question you were given
3x + 6+x =2x +16
3)group the x variables and the non x variables
3x +x -2x =16 -6
4) Now work the equation you have
3x+x-2x=16-6
4x-2x=16-6
2x=16-6
2x=10
5) you divide both sides by the x variable
2x=10
2x/2 =10/2
x=5
therefore x is 5
Answer:
C
Step-by-step explanation:
The secant- secant angle ACE is half the difference of the measures of the intercepted arcs, that is
∠ ACE = 
(AE - BD ) = (104 - 46)° = × 58° = 29° → C
Y + 2 = -2(x - 5)
Simplify.
y + 2 = -2x + 10
Subtract 2 from both sides.
y = -2x + 10 - 2
Simplify.
y = -2x + 8 → Slope-intercept form
Our answer is the second option : y=-2x+8
~Hope I helped!~
