Question 606993
1	x	+	5	y	=	28	.............1			
5	y	=	28-	x				
/	5	=								
	y	=	5.6-0.2	x
				
-2x+y	=	-1				
Substitute y in		(2)								
-2x+1(5.6-0.2x)=-2x+5.6	-0.2x=-1		
-2x-0.2x=-6.6				
-2.2	x	=	-6.6							
/	-2.2									
x=	3      									
Plug the value of x in (1)										
x+5y=28				
1*3+5y=	28			
3      	+	5	y	=	28					
5	y	=	25      							
/	5									
y=	5
