Question 1123813

solve the simultaneous equation: 

1.)   log2^x - log2^y =2, log2^(x-2y) = 3 
<pre>If it's {{{system(matrix(1,3, log (2, (x)) - log (2, (y)), "=", 2), and, matrix(1,3, log (2, (x - 2y)), "=", 3))}}}, then {{{highlight_green(matrix(1,7, x, "=", 16, and, y, "=", 4))}}}. 
If not, you're on your own!
