**Reiny**, Tuesday, July 13, 2010 at 8:00pm1st one times 5, 2nd one times 2

1.5x - y = 20

.8x + y = -110/17

add them

2.3x = 230/17

x = 100/17

plug this back into 1.5x - y = 20

1.5(100/17) - y = 20

-y = 20 - 150/17

y = -190/17

weird equations, weird solutions, but they are right, I checked them
