4. 7(x-2) /(x-2) = 7 * 1 = 7
but x may not be 2 or the original denominator would be zero

15. haha here's my last question

Suppose that y varies inversely with x and that y = 4 when x = 6. What is an equation for the inverse varition?

y = 6/4x

y = 24/x

y = 2/3x

y = x/24

16. y = k/x

4 = k/6

k = 24
so
y = 24/x

Just do what it says :)
