Answer:
p = -3
Step-by-step explanation:
Solve for p:
-2 p - 4 = 2
Add 4 to both sides:
(4 - 4) - 2 p = 4 + 2
4 - 4 = 0:
-2 p = 2 + 4
2 + 4 = 6:
-2 p = 6
Divide both sides of -2 p = 6 by -2:
(-2 p)/(-2) = 6/(-2)
(-2)/(-2) = 1:
p = 6/(-2)
The gcd of 6 and -2 is 2, so 6/(-2) = (2×3)/(2 (-1)) = 2/2×3/(-1) = 3/(-1):
p = 3/(-1)
Multiply numerator and denominator of 3/(-1) by -1:
Answer: p = -3
Add +4 to both sides of the equation to get -2p = 6. Divide both sides by -2. -2/-2 = 1, and 6/-2 = -3. Therefore, p = -3. You can check your work through substitution: -2(-3) - 4 = 2. 6 - 4 = 2.
Answer:1/n - 2/n= -1/n
Answer: not and identity
The two given angles are vertical angles and equal each other:
3x + 50 = 6x -10
Now solve for x:
Subtract 3x from both sides:
50 = 3x -10
Add 10 to both sides:
60 = 3x
Divide both sides by 3
X = 20
