What is the inverse variation of xy=7

y=7/x

300

6/x=2/9

x=27

400

6/x+5=3

x=-3

500

1/3+1/x=3/x

I Got This

100

16/3 / -4

-4/3

200

4/(x-1)=3/(x+1)

x=-7

300

4/(x-3)+5/(x-3)

9/(x-3)

400

1/6m+5/6m

1/m

500

2/x+2+2=7/x+2

x=1/2

I Should Know This

100

factor 9-36

(3-6)(3+6)

200

(w-4)^2/(4-w)^2 / w^2-16/(w-2)

(4-w)/(w+2)(w+4)

300

(2x-3)/3/(6x-9)

1/9

400

formula for difference of cubes?

(a-b) (a^2+ab+b^2)

500

x=2-x/6x

(-2/3;1/2)

I Have No Idea

100

(r-4)/3r + 2/5r = 1/5

r=7

200

t^2/(t^2-16) / (t^2-3t)/ (t^2-t-12)

t(t+3)/(t+4)(t-3)

300

(x+1) X (x-6)/(x^2-5x-6)

400

3/(x-y) + 10/(y-x)

- 7/(x-y)

500

3/(2x+2) - 5/ 4(x-1) = 2x/ (x^2-1)

x=-11/7

Good Luck

100

X^2/ (3x^2 + 5x -2) - x/ 3x-1 X (2x-1)/ (x+2)

-x(x-1)/ (3x-1)(x+2)

200

x^2 + 3xy +2y^2 / x^2-y^2 X (3x-3y) / (9x^2+9xy-18y^2)

1/3(x-y)

300

2x/x+4 = x+1/ x+2 - 7x+12/ x^2 + 6x +8

no solution HAHAHAHAHA
