The number is #-1#

Use the information give to write an equation and solve it.

Let the number be #x#

'Twice a number' means # 2 xx x = 2x#

'#4# more than twice a number' means: #2x +4#

The answer to this must be #2#. Show it as:

#2x+4 = 2" "larr# now solve the equation you have written.

#2x +4 color(blue)(-4) = 2color(blue)(-4)#

#2x = -2" "larr div 2#

#x =-1#

Check: #(2xx -1) +4 = 2#
