Select and write the correct answer from the given alternatives in each of the following:If [[2x+1,-1],[3,4y]]+[[-1,6],[3,0]]=[[4,5],[6,12]] Then find the value of x and y

Evaluate |(-1, 0,0),(2,3,0),(-6,-4,5)|

If A = [[x,1,-x],[0,1,-1],[x,0,7]] and det (A) = |(3,0,1),(2,-1,0),(0,6,7)| , then the value of x is a)-3 b)3 c)2 d)-8
