how will you solve this x+y=311 and .50x=1.50y=38550 by solving systems by elimination
x + y = 311 ---> (multiply by 3) ---> 3x + 3y = 933
.5x - 1.5y = 38550 ---> (multiply by 2) ---> x - 3y = 77100
(add down the columns) ---> 4x = 78033
x = 19508.25
x + y = 311 ---> 19508.25 + y = 311 ---> y = -19197.25
