If y varies inversely as x, and y = 4 when x = 16, what is the value of y when x = 8?

4 0

I suppose that the value of y equals 2, seems how 4 times 2 what equal 8 and 8 times 2 would equal 16

To solve this we need to use this formula:

$a(b + c) = ab + ac$

$5(3x + 2) - 2(4x - 1) = 15x + 10 - 8x + 2 = \\ = 7x + 12$
