Answer:
x=4
Step-by-step explanation:
-3x+12-12=x-4-12
-3x=x-16
-3x-x=x-16-x
-4x=-16
-4 divided by -16
x=4
Answer:
The equation of the line will be 
Step-by-step explanation:
If a line passes through two points (x,y) and (x',y') then slope of the line will be = 
Now we know the points are (-3,4) and (4,-1) then the slope of the line will be =
=
)
We know that two parallel lines have the same slope then a line which is passing through a point (-1,8)will be =(
)
Let the equation of the line is y=mx+c
Then by putting the value of x,y and m we can get the value of c.


Then equation will be 

Step-by-step explanation:
As < A and < B are vertical angles so
<A = < B
5x + 12 = 6x - 11
6x - 5x = 12 + 11
x = 23
