Put (-2) where x is, then evaluate.
  3(-2) + 2 - (4(-2) + 5)
  = -6 + 2 - (-8 + 5)
  = -6 + 2 -(-3)
  = -6 + 2 + 3
  = -4 + 3
  = -1

The equation is: 3x +2 -{4x+ 5}

grouping the similar variables together, we have
3x +2 - 4x - 5
applying the value of x
=3(-2) + 2 -4(-2) -5
=-6 + 2 + 8 -5
=-1
hence value of equation is -1
