Answer:
x=-3
Step-by-step explanation:
Move the 9 to the other side of the equal Sign making it negative
Then also move the -30 to the other side to isolate the term 9x
-3 + 30 = 27
Divide both sides (which should now have -9x = 27) by -9x to isolate the variable
27/-9x = -3
As all fractions are simply an instance of division that wouldn't yield a whole number as a result, to get this answer you should simply divide all of these out.
Answer:
Step-by-step explanation:

Step-by-step explanation:
1) r+28=180( being linear pair angle)
r=180-28
r=152
2) a= 110( being vertically opposite angle)
Answer:
nj+k = p
Step-by-step explanation:
n = (p-k)/j
Multiply each side by j
nj = (p-k)/j *j
nj = p-k
Add k to each side
nj +k = p-k+k
nj+k = p
