Question 1013965

 If x and y are positive whole numbers, what is the smallest value of x + y such that 2x + 5y is divisible by 16? 
I know the answer is 5 but cant figure out how
I need to be shown how to work out it out 
<pre>The "6" in 16 MUST be a result of being multiplied by 2: the coefficient on x, hence: {{{6/2}}}, or 3: the value of x. 
With x being 3, we get:
2(3) + 5y = 16
6 + 5y = 16
5y = 16 - 6
5y = 10______y = {{{10/5}}}, or 2
With x = 3, and y = 2, {{{highlight_green(x + y = 3 + 2 = 5)}}}
