985x3678y is divisible by 72 $\left(9\times 8\right)$
if this number is divisible by 8 then last three digit is also divisible by $8=\mathrm{}\frac{78\mathit{y}}{8}$ is divisible
o, y must be 4 if 985x36784 is divisible by 9 then sum is also divisible $=\mathrm{}\frac{50+\mathit{x}}{9}$ is divisible
x must be 4
find, $4\mathit{x}-3\mathit{y}$
$4\times 4-3\times 4$
$=16-12$
$=4$
