Answer:(x,y)=(2.5,1)
Step-by-step explanation:
Given


thus on comparing  
2x+y=6------1


On comparing exponent of 2
 ------2
 ------2
we get x=2.5
substitute x in 1
y=1
(x,y)=(2.5,1)

6/12 and 4/8 are equal fractions, as, when simplified, they share a simplified fraction. 
Note that what you do to the denominator, you do to the numerator. Find common denominators for both fractions: 
(4/8)/(2/2) = 2/4
(6/12)/(3/3) = 2/4
As you can tell, when they share a common denominator (4), the numerators are the same as well (3).
