The answer is: #abs(x) = 2x+5#

Given:

#P# is a point on the #x#-axis.
The distance between the origin and #P# is #5# more than twice of the value of #P#

Absolute value operator gives us the distance from any point to the origin.

For example:

#abs(5) = abs(-5) = 5#

Lets say that #P# is #(x,0)#

The distance from point #P# to origin is:

#(x,0) - (0,0) = 2x+5#

#(x,0) - (0,0) -= abs(PO)#

So the result is:

#abs(x) = 2x+5#
