Answer:
Step-by-step explanation:
interchange x and y
y= 1/(x - 2)
x = 1 / (y - 2)      Multiply both sides by y - 2
x(y - 2) = 1          Remove the brackets
xy - 2x = 1          Add x to both sides
xy = 1 + 2x         Divide by x
y = (1 + 2x)/x
The brackets have been destroyed. The answer is as I've given it.
y = (1/x) + 2

To find the GCF:
-- List the factors of the first number.
-- List the factors of the second number.
-- Make a short list of the factors that show up for BOTH numbers.
-- Find the biggest number on the short list.
Factors of the first number (99):  <u>1</u>, 3, 9, <u>11</u>, 33, 99 .
Factors of the second number (121):  <u>1</u>, <u>11</u>, 121 .
Short list (factors that show up for both numbers):  1, 11
Biggest number on the short list:  <em>11</em>
