Answer:
n = (2 i π k)/log(3) - 2 for k element Z
Step-by-step explanation:
Solve for n:
3^n = 1/9
Take the logarithm base 3 of both sides:
Answer: n = (2 i π k)/log(3) - 2 for k element Z

Answer:
x=3 and y=4
Step-by-step explanation:
solve x-y=-1 to get x:
x−y=−1
x−y+y=−1+y(Add y to both sides)
x=y−1
Substitute y−1 for the x value in x+2y=11:
3y/3=12/3
y=4
Substitute 4 for the y value in x=y−1:
x=y−1
x=4−1
x=3
so y=4, and x=3
