Answer:
-20x / (x-12) = y
Step-by-step explanation:
3/x - 5/y = 1/4
Multiply each side by 4xy to clear the fractions
4xy ( 3/x - 5/y = 1/4)
Distribute
12y - 20x = xy
Subtract 12y from each side
-20x = xy -12y
Factor out y
-20x = y(x-12)
Divide each side by (x-12)
-20x / (x-12) = y

Answer:
-0.1 and 0.1
Step-by-step explanation:
A fourth root is a number which multiplied by itself 4 times gives 0.0001.
Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.
0.1*0.1*0.1*0.1 = 0.0001
So the real fourth roots are -0.1 and 0.1.
