`|(3, 5, x), (7, x, 7), (x, 5, 3)|` = 0

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

If |(x,3,6),(3,6,x),(6,x,3)|=|(2,x,7),(x,7,2),(7,2,x)|=|(4,5,x),(5,x,4),(x,4,5)|=0 , then x is equal to a)9 b)-9 c)0 c)-1

If A=[{:(1, 3/5, x),(y, -5, -7),(-4,-7,0):}] is a symmetric matrix then the value of x and y are ______

If |{:(x,3,6),(3,6,x),(6,x,3):}|=|{:(2,x,7),(x,7,2),(7,2,x):}|=|{:(4,5,x),(5,x,4),(x,4,5):}|=0 then x is equal to

If |{:(x,3,6),(3,6,x),(6,x,3):}|=|{:(2,x,7),(x,7,2),(7,2,x):}|=|{:(4,5,x),(5,x,4),(x,4,5):}|=0 then x is equal to

" if " |{:(x,,3,,6),(3,,6,,x),(6,,x,,3):}|= |{:(2,,x,,7),(x,,7,,2),(7,,2,,x):}|=|{:(4,,5,,x),(5,,x,,4),(x,,4,,5):}|=0 then x is equal to

" if " |{:(x,,3,,6),(3,,6,,x),(6,,x,,3):}|= |{:(2,,x,,7),(x,,7,,2),(7,,2,,x):}|=|{:(4,,5,,x),(5,,x,,4),(x,,4,,5):}|=0 then x is equal to

Solve for x : |(x-2,2,5),(x-7,3,6),(2x-6,4,7)|=0

|[3+x,5,2] , [1,7+x,6], [2,5,3+x]|=0

Add : 3x, - 5x , 7x
