Question

Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this
4x – 5y = -31
-12x + 15y = 93

Answer 1

are you still there??

Answer 2

yes

Answer 3

lets start by eliminating y :\[~3~(4x ~–~ 5y ~= -31)\]\[-12x + 15y = 93\] \[12x-15y=-93\]\[-12x+15y=93\] \[0=0\]
as you can see this results in 0=0 and that means that there are an 'infinite number of solutions'.
