Move all y terms to both sides
subtract both sides by 3xy
<span>y=3xy-1
y - 3xy = -1
factor out y from the left side: y(1 - 3x) = -1
divide both sides by (1-3x)
y = -1/(1-3x)

Answer:
k=2
Step-by-step explanation:
3^k*2 * 3^-k+2 = 81
Factor out 81 to be : 3^4
Rewrite the equation:
k*2 - k+2 = 4
k^2 - 2k = 4
Simplify : k+2 = 4
<u> - 2 - 2</u>
k = 2
Answer:
387.
Step-by-step explanation:
Given : 3-6(z-2)³.
To find : What is value if z = -2.
Solution : We have given
3-6(z-2)³.
Plugging the z = -2
3 - 6( -2- 2)³.
3 - 6( -4)³.
3 - 6 ( -64).
3 + 384.
387
Therefore, 387.
