The answer is C) NO solution.
5 - 15n = -5(3n - 2)
5 - 15n = -15n + 10
5 = 10
Since 5 = 10, its false so no solution.
Answer:
x=8°
y=29°
Step-by-step explanation:
vertically opposite angles are equal
so 5x+9°=y+20°
therefore 5x-y=11°
Alternate angles are equal
so 4x+17°=y+20°
therefore 4x-y=3°
equation 1....... 5x-y=11°
equation 2......4x-y=3°
using elimination method x=8°
y=29°
