- 4x from 8x = 4x
-9 + 19 = 4x -14
-9 + 19 = 10
10 = 4x -14
+14
24 = 4x
divide by 4
X = 6
In my opinion I think it's letter d
Answer:
C
Step-by-step explanation:
Supplementary angles because their sum is 180 degrees
N + 4 / 3 = 1 / 3
Multiply both sides by 3 :
3* ( N + 4 / 3 ) = 3 * ( 1 / 3 )
∴
N + 4 = 1
Subtract 4 from both sides:
N + 4 - 4 = 1 - 4
N = - 3
