5y=7x+22
x=-6y+17

Re write the equations



-7	x	+	5	y	=	22	.............1		
1	x	+	6	y	=	17	.............2		
Eliminate	y								
multiply (1)by		-6							
Multiply (2) by		5							
42	x		-30	y	=	-132			
5	x	+	30	y	=	85			
Add the two equations									
47	x				=	-47			
/	47								
x	=	-1      							
plug value of			x	in (1)					
-7	x	+	5	y	=	22			
7    		+	5	y	=	22			
			5	y	=	22		-7      	
			5	y	=	15      			
				y	=	3
