Find the value of x, if |[(3+x), 5, 2],[1, (7+x), 6], [2, 5, (3+x)]| = 0

If (9x -5)/(7) + (6 -3x)/(2) =2 , then x = _____

If x=-9 is a root of |(x,3,7),(2,x,2),(7,6,x)|=0 , then the other two roots are

If x = -9 is a root of |{:(x,3,7),(2,x,2),(7,6,x):}|=0 , then other two roots are ".........." .
