Question 424291
5x+6y=-75x-3y=146

You should separate the equations with a colon
5x+6y=-75 : x-3y=146

5x+6y=-75.............1				
-3y=146	-1x					
/-3									
y=-48.67-0.33x					
Plug the value of y in (1)											
5x+6(-48.67+0.33	x)=-75
5x-292+2	x)=-75			
5x+2x=-75+292				
7x=217								
/7										
x=31										
Plug the value of x in (1)											
5x+6y=-75					
5*31+6y	=-75				
155+6y=-75						
6y=-230								
/6									
y=-38.33
