12x+5y=34
-6x+5y=3
what do x and y equal

Step-by-step explanation:

12x + 5y = 34

 6x - 5y = -3

18x = 31

x = 31/18

-6(31/18) + 5y = 3

-31/3 + 5y = 9/3

5y = 40/3

15y = 40

y = 40/15

y = 8/3

(31/18, 8/3)

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
