Answer:
1) Add 3n to both sides
2) Subtract 5 from both sides
3) Divide both sides by 6
n=3
Step-by-step explanation:
3n+5=23-3n
+3n +3n
6n+5=23
-5 -5
6n=18
/6 /6
n=3
Answer:
34 degrees
Step-by-step explanation:
considering the two lines are parallel:
(3x + 7) + (2x + 3) = 180 degrees
3x + 2x + 7 + 3 = 180 degrees
5x + 10 = 180
5x = 180 - 10
5x = 170
x = 170/5 = 34
the value of x = 34 degrees
