Question 457531
0.3x-0.2	y=4	.............1	
0.5x+0.5	y=1.96	.............2	
								
multiply (1)by 		0.5						
Multiply (2) by		0.2						
0.15x-0.1y=2		
0.1x+0.1	y=0.39		
Add the two equations								
0.25x=2.39		
/0.25							
x=9.57						
plug value of 			x	in (1)				
0.3x-0.2	y=4		
2.87-0.2	y=4		
-0.2y=4-2.87
-0.2y=1.13		
y=-5.65
