The number is #color(blue)(=-20#

Explanation:

Let us denote the number as #x#

  • Three times the number #=3x#
  • Five times the number #=5x#
  • #40# more than #5# times the number = #5x +40#

As per data provided we arrive at the below expression:

#3x=5x+40#

#3x-5x=40#

#-2x=40#

#x=40/(-2)#

#color(blue)(x=-20#
