Step-by-step explanation:

Given If the value of determinant is 31 find the value of x

  • Given determinant x    2
  •                  So       - 5    7        =  31
  • We need to find the value of x
  • Therefore we have
  •               So x x 7 – (2 x – 5) = 31
  •               So 7x – (- 10) = 31
  •               So 7x + 10 = 31
  •               Or 7x = 31 – 10
  •                Or 7x = 21
  •                Or x = 21/7
  •               Or x = 3
