Let $\displaystyle \mathrm{a}, \mathrm{b}, \mathrm{c}$ and d be non-zero numbers. If the point of intersection of the lines $\displaystyle 4 \mathrm{a} x+2 \mathrm{a} y+\mathrm{c}=0$ and $\displaystyle 5 \mathrm{~b} x+2 \mathrm{~b} y+\mathrm{d}=0$ lies in the fourth quadrant and is equidistant from the two axes then :
Official answer
(1)
$\displaystyle 3 b c-2 a d=0$
