A 3-digit integer is called a "V - Number" if the digits go 'high-low-high'. What that means is if the ten's digit is smaller than both the hundred's digit and the one's digit, it is a V-number (example: 314). How many 3-digit V-Numbers are there?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
