Question 1159361


Let number of heavy equipment operators be x
and laborers be y
Thirty-two people were hired


x+y =32

Heavy equipment operators $ 132 per day
and general laborers $81 per day
 the payroll was $3510,
132x + 81y = 3510

	x	Heavy equipment operators			$	132					
	y	labourers			$	81					
											
											
1.00	x	+	1.00	y	=	32.00					
											
											
132.00	x	+	81.00	y	=	3510.00	.............2				
Eliminate 	y										
multiply (1)by		-81.00									
Multiply (2) by		1.00									
-81.00	x		-81.00	y	=	-2592.00					
132.00	x		81.00	y	=	3510.00					
Add the two equations											
51.00	x				=	918.00					
/	51.00										
x	=	18.00									
plug value of			x	in (1)							
1.00	x	+	1.00	y	=	32.00					
18.00		+	1.00	y	=	32.00					
			1.00	y	=	14.00					
				y	=	14.00					
Ans	x	=	18.00								
	y	=	14.00								
	18	Heavy equipment operators									
	14	labourers									




 how many heavy equipment operators were​ employed?  How many​ laborers?
