Question 632735: solve using the elimination method. show your work. if the system has no solution or an infinite number of solutions, state this. -12x+27y=60
-6x-6y=30

You can put this solution on YOUR website!
-12 x + 27 y = 60.00 .............1
-6x-6y=30
/6

-1 x -1 y = 5.00 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by -27
-12 x 27 y = 60.00
27 x + 27 y = -135.00
Add the two equations
15 x = -75.00
/ 15
x = -5.00
plug value of x in (1)
-12 x + 27 y = 60
60 + 27 y = 60
27 y = 60 -60
27 y = 0
y = 0.00
x=-5,y=0
