Answers: 2
and 
.
and 
, we can write the following system of equations to solve for them:
(since the sum - which indicates addition - of the two numbers is 
)
(since the difference - which indicates subtraction - of the two numbers is 
)
(Add the two equations together)
(Divide both sides of the equation by 
to get rid of 
(Substitute 
(Add 
to both sides of the equation to isolate Another question on Mathematics
