a television addict can buy either two televisions and three video recorders for $1750 or four televisions and one video recorder for $1250. find the cost of one of each.

---------------------

Let cost of TV's be "t"; Let cost of VCR's be "v"

--------------

EQUATIONS:

1st: 2t+3v=1750

2nd: 4t+ v=1250

-------------

Multiply 1st be 2 to get:

3rd: 4t+6v=3500

------------------

 

Subtract 2nd from 3rd to get:

5v = 2250

v = 450 (cost of a Video Recorder)

-------------

Substitute into 2t+3v=1750 to solve for "t":

2t+3*450=1750

2t+1350 = 1750

2t = 400

t = 200 (cost of a TV)
