Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot each equation.
Please see the attached image below, to find more information about the graph
s
The equations are:
1) y = sin (3x + π/6)
2) y = cos (3x - π/6)
3) y = cos (3x - π/3)
Looking at the graphs, we can see that the identical ones
are equations one and three

Answer:
n=-14
Step-by-step explanation:
2n+18-n=-10-n
n+18=-10-n
+n        +n
2n+18=-10
-18      -18
2n=-28
/2     /2
n=-14
