181 and 169

This is a simultaneous equation problem.

Let #x# be one of the numbers, and #y# be the other.
#x+y=350#
#x-y=12#

Let's solve by eliminating b since one of the equation is #+y# and the other is #-y#.

Add the two equations

#2x=362#

Divide both sides of the equation by #2#

#x=181#

Substitute #x=181# into either of the equations

If you chose the first one,

#181+y=350#

Take away 181.

#y=169#

If you chose the second one,

#181-y=12#

Add #y# to both sides

#181=y+12#

Take away 12 from both sides

#y=169#
